If you&#;re ready to expand your family and want to be pregnant, it may feel like there&#;s not a month to miss!
Even if you just decided to start trying, every month that passes without a positive pregnancy test may seem like forever as you wonder if and when your family might expand.
If you&#;d like to maximize the likelihood of becoming pregnant, you may be willing to try just about anything! Well, starting with ovulation test strips may help you take control of your fertility.
Ovulation test strips are similar in design to the pregnancy tests found in many convenience and grocery stores. But instead of indicating when you&#;re pregnant, ovulation test strips indicate your fertile window so you&#;ll know when intercourse is most likely to result in a pregnancy.
Much like the store bought pregnancy tests that detect human chorionic gonadotropin (hCG) levels in your urine, ovulation test strips detect luteinizing hormone (LH) in your urine to tell you when you&#;re most likely to conceive. How is this possible? It&#;s all thanks to an LH surge&#;
Luteinizing hormone is secreted at low levels throughout your menstrual cycle. However, once a developing egg follicle reaches a certain size, levels increase and an LH surge causes ovulation to occur 24 to 36 hours later. (If you&#;re wondering about the timeline involved, this surge usually occurs around the midpoint in your cycle.)
So, what does all this mean? If you&#;re trying to get pregnant, ovulation is important, as it signifies the culmination of the fertile window. Once an egg has been released from the ovary, it&#;s only viable for 24 hours.
Your best chance of becoming pregnant involves having unprotected intercourse from 5 days before to 1 day after ovulation. This means by the time you see the LH surge, you&#;re already in the middle of your fertile window.
To put it simply, an LH surge indicates it&#;s time to have unprotected sexual relations if you want to become pregnant. A good rule of thumb for conception is to have sex 2 to 3 times in the 24 to 48 hours following your LH surge.

It&#;s important to note that using ovulation test strips doesn&#;t guarantee you&#;ll become pregnant. For one, they don&#;t work for everyone. There are cases (some of which are described below) in which the body has an elevated LH level due to other reasons, and an LH surge won&#;t indicate ovulation.
Additionally, ovulation test strips do not test the viability of eggs or sperm, and they don&#;t affect fertilization. As such, there&#;s no guarantee that if you have sex during an LH surge you&#;ll conceive a healthy baby.
If you have concerns about whether you&#;re ovulating &#; or any other factors that may affect your ability to conceive &#; you should speak to your healthcare provider about further testing options.
The various brands of ovulation test strips come with slightly different directions, so it&#;s important to check the instructions on your particular kit!
In general, you&#;ll want to use the ovulation test strips at the same time each day for several days until you get a positive result. The process is typically a very simple one that involves dipping the test strips in urine and waiting to read the results.
Knowing which days to use your ovulation test strips can be complicated. Due to the cost of test strips, most people don&#;t want to test every day of the month, so it&#;s helpful to narrow in on a window of a few days to test.
If you&#;re using test strips and would like to skip the math, one option is to use an ovulation calculator app. Just insert some information about your average period length and the dates of your last cycle, and presto, you&#;ll have an estimated ovulation date.
Simply begin using your strips a few days before your estimated ovulation date to make sure that you don&#;t miss the LH surge if you have a shorter than usual cycle. With any luck, you&#;ll be looking at a positive pregnancy test in a few weeks.
Curious about the math and want to try to figure it out on your own? Well, in a 28-day cycle, ovulation typically occurs about 14 days after the first day of your last period, and your LH surge generally occurs 1 or 2 days before that. In this case, you&#;d begin testing around day 10.
If your cycle is shorter or longer, you&#;ll need to adjust the midpoint. You should begin testing at least 3 to 4 days before your estimated ovulation date to catch the surge.
If you are using basic test strips, you&#;ll see two lines. One line is the control line. This is just to let you know that the test is working properly. The other line is the test line. You can tell that LH is surging when this second line is as dark or darker than the control line.
If you&#;re using an ovulation test with a digital display, a design will appear on the screen indicating whether you&#;ve entered your fertile window.

When your test appears positive, you&#;ll know that your LH surge is taking place and that your fertile window is the next 24 to 48 hours.
Keep in mind that you can get a positive result on your test for several days, so if your first day of testing is positive, next month you may want to test a day or two earlier to ensure you catch the start of your LH surge. As mentioned earlier, your fertile window begins a few days before the surge, so knowing when it happens can help pinpoint your timing.
There are many different types of ovulation test strips &#; and a range of prices to go along with them!
More expensive options offer a digital display, and some detect both estrogen and LH. This allows them to detect more fertile days than some of the basic tests.
You&#;ll spend more money for this information and ease of readability, but the extra information may be worth it if you&#;ve been struggling to conceive. (You&#;ll also need to start testing at a different time with these digital display options, so make sure to read the directions carefully!)
On the other end of the cost spectrum, you can buy ovulation test strips in bulk online that&#;ll come with limited directions for use. Whether these test strips will work for you depends on your comfort with reading them.
Unlike pregnancy tests, which either show a line or not, you&#;ll need to be able to compare the color of the test line to the control line on a basic ovulation test strip. To make this easier, some brands offer an app to track your tests and compare the lines over time.

Ovulation test strips are not a fit for everyone, so it&#;s important to know that you may not want to use them if:
Once baby fever hits, it can be hard to wait! If you don&#;t want to waste any time getting pregnant, current medical technology can certainly increase the likelihood of your wish coming true. Before skipping to more invasive procedures, though, you may want to consider giving ovulation test strips a try.
Ovulation test strips can&#;t guarantee a pregnancy, but they can help you know what your fertile days are. If you&#;re not a good candidate for ovulation strips or you need additional assistance, talk to your medical provider. They can use blood tests to determine your fertile period, or maybe even do a transvaginal ultrasound to check your uterus and ovaries.
Also, don&#;t be afraid to talk with your provider if you find that you&#;re not able to conceive after 6 months of trying (if you&#;re 35 years or older), or for more than 1 year (if you&#;re under 35 years old). Your doctor can offer further assistance or direct you to a fertility specialist.
Luteinizing hormone (LH) is one of the essential hormones for human sexual and reproductive health. Together with follicle Stimulating Hormone (FSH), luteinizing hormone (LH) helps induce and regulate reproductive function in both men and women. Although it is regulated by an endocrine circuit responsible for regulating reproductive function called the hypothalamic&#;pituitary&#;gonadal axis, abnormal levels of luteinizing hormone (LH) can cause a wide array of common and significant medical issues such as infertility, menstrual problems, and low sex drive, along with early or delayed puberty in children. In addition to assisting in the identification of the underlying reasons for these conditions, screening of the level of luteinizing hormone (LH) can also help predict the fertility cycle for females and determine the optimal time for conception. Today, lateral flow tests, such as our Ovulation LH Rapid Test Kit, are among the most convenient and effective methods to check for the level of luteinizing hormone (LH). Read along to learn more about the process of ovulation, the functions of the luteinizing hormone (LH), and how to use the Ovulation LH Rapid Test Kit for the detection of the luteinizing hormone (LH).
Ovulation is a phase in the menstrual cycle when the ovary releases a mature egg (ovum). The process of ovulation starts with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. Gonadotropin-releasing hormone (GnRH) signals the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Between days six and 14 of the menstrual cycle, the follicle-stimulating hormone (FSH) causes follicles in one ovary to develop. One of the developing follicles develops into a fully mature egg throughout days 10 to 14 of the menstrual cycle. Then, approximately on day 14 in the menstrual cycle, luteinizing hormone (LH) peaks rapidly to cause the ovary to release the fully mature egg to make it available for fertilization. The most common signs of ovulation include changes in vaginal secretions, changes in basal body temperature, discharge, spotting, mild pelvic/abdominal pain, bloating, tenderness in breasts, and mood swings.
Once the egg is released by the ovary, it enters and travels through the fallopian tubes, where it meets sperm for fertilization. If conception occurs, the fertilized egg travels down to the uterus and attaches to the uterine lining, which is referred to as implantation. After ovulation, levels of estrogen and progesterone rise to help the endometrium to thicken and prepare the uterus for the arrival of the fertilized egg. If conception does not occur, the unfertilized egg and the lining of the uterus are shed through a process called menstruation.
Luteinizing Hormone (LH) is a gonadotropic hormone secreted by the anterior pituitary gland in response to the gonadotropin-releasing hormone (GnRH) secretion by the hypothalamus. Together with follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG), luteinizing Hormone (LH) is categorized as gonadotropin as its function primarily involves the gonads, which are testes and the ovaries. In females, luteinizing Hormone (LH) regulates the process of ovulation and facilitates the formation and maintenance of the corpus luteum. In males, luteinizing Hormone (LH) induces the production of androgens in the Leydig cells of the testes.
The Ovulation LH Rapid Test Kit is a rapid chromatographic immunoassay for the qualitative detection of human luteinizing hormone in urine to predict the time of ovulation. Coming in a lateral flow test format, the test kit utilizes LH-specific labeled antibody-dye conjugates and immobilized anti-LH antibodies to detect and capture LH-specific antigens. As the urine sample migrates along the absorbent test strip via capillary flow, LH-specific labeled antibody-dye conjugates bind to the LH antigens present in the sample and form antibody-antigen complexes. These complexes migrate further to the test region (T) and are captured by a line of immobilized anti-LH antibodies, which appears as a colored line in the test region (T) if the concentration of LH in the collected sample is within detectable levels. Regardless of the presence of the test line (T), the labeled antibody-dye conjugates bind to the reagents in the control region (C) to produce a colored line as procedural control.
The test kit can accurately detect a surge when the concentration of LH within the tested urine sample is equal to or greater than 25mIU/ml. However, certain prescription drugs or medical conditions can interfere with the test results. For example, the onset of menopause may cause elevated levels of LH. Likewise, polycystic ovary syndrome (PCOS) may cause irregularities in LH levels that may affect the results of ovulation tests. Moreover, some women do not ovulate every cycle and may not see any surge in the level of LH hormone during these non-ovulating cycles.
The test procedure requires a urine sample to be collected in a clean and dry container. Following the collection of the urine sample, all components of the test kit should be brought to room temperature before they are removed from their packages. Next, the test strip is removed from its sealed pouch and inserted into the collected urine sample as soon as possible without passing the maximum line. The strip is left within the sample for a few seconds, as instructed. Then, the strip is placed on a clean and flat surface. The results are read after 5 to 10 minutes. If both the test line (T) and the control line (C) are present after the reaction time specified in the manual, the test result is positive. If only the control line (C) is present, the result is negative. The absence of the control line (C), on the other hand, indicates an invalid result. As the control line (C) functions as an internal procedural control that confirms sufficient specimen volume and correct procedural technique, it should always appear regardless of the presence of the test line (T). If the control line is absent at the end of the period specified in the manual, the procedure should be repeated with a new test kit.
