Read Everything. You may have heard that ovulation tests can be used to test for pregnancy. Ovulation usually occurs 12 to 36 hours post surge but some women may ovulate a bit earlier and others a bit later.
This is why confirming ovulation is so important! Although they both have two lines and use urine, ovulation and pregnancy tests are not the same. As we know, ovulation tests measure LH in urine to predict ovulation. Pregnancy tests, on the other hand, measure human chorionic gonadotropin hCG to confirm pregnancy.
Yet, you may have heard some women claim that an ovulation test can detect early pregnancy. How could this even happen? Both LH and hCG are proteins that are built with a sugar attached to them. Their functions are completely different, with LH triggering ovulation and hCG maintaining pregnancy. Yet their structures are very similar!
The presence of hCG confirms, without a doubt, that you are in fact pregnant. An LH test on the other hand may occasionally turn positive in early pregnancy could be misleading as some women just have high LH levels throughout their cycle.
Some women even get a second LH surge just before their period, so an ovulation test could be detecting this instead of pregnancy. To be confident in your test results, we recommend using each test as directed!
Implantation can occur anytime between days 6 through 12 after ovulation. Studies actually show that the most common implantation day is day 9 post ovulation. Once implantation occurs, it can take about 24 hours for hCG to show up in your urine. So while some home pregnancy tests claim to detect early pregnancy, they technically cannot detect hCG until it appears in urine. Both are important on your TTC journey!
Shop Fertility Tests. Ovulation predictor kits have two lines. One line is the control line. This just lets you know that the test was used properly and is working.
The second line is the test line. When the test line is as dark or darker than the control line, LH is surging. This is when you should start having baby-making sex. Clearblue Easy Fertility Monitor works differently from regular ovulation predictor kits.
You need to start testing on the first day of your period. Whatever ovulation test kit you use, be sure to read the instructions carefully for the best results. Relatively easy to use. Unlike BBT charting, they tell you when ovulation is approaching , not that it's already passed. Morning urine is best, but taking the test within the same six-hour window every day should give accurate results. If you're not comfortable checking for cervical mucus , you may feel better using the test strips.
Using one month after month can get expensive. This is especially so if your cycles are irregular and you need to use more than five test strips. Some people have trouble reading a positive ovulation test result.
Ovulation tests may not work well for women with polycystic ovarian syndrome, who can have several LH surges or high levels of LH throughout their cycles. Since ovulation kits test for LH, they may yield positive results all the time or on several days. These positive results are false-positives—they don't mean you're ovulating. They can signal that your body is trying to ovulate, but they can't confirm that ovulation happened. It's possible for LH to surge and an egg to never release.
While ovulation predictor kits cannot confirm that ovulation actually took place, body basal temperature charting can. Ovulation predictor kits can be used alongside other methods of ovulation detecting, like BBT charting. This can give you more assurance and help you get to know your body better. You may want to use an ovulation predictor kit when you just start fertility charting for added confidence.
Once you get the hang of charting your BBT and cervical mucus, you can drop the expensive ovulation test strips. For women who find fertility charting stressful, though, ovulation predictor kits can be a great way to predict ovulation and time sex for pregnancy. Why might this happen? One possible reason is you started testing too early in your cycle.
Day 17 would be your last test day. Another possibility is you started testing too late. In this situation, you may miss the LH surge. This is one reason it helps to have an idea of when you tend to ovulate depending on the length of your cycle.
The longer your cycles are, the more likely it is that you ovulate later than average. The shorter your cycles are, the more likely it is that you ovulate earlier than average. You can find a helpful chart on this page that will tell you the best time to start testing, depending on your cycle length.
You may have heard that ovulation tests can be used to detect pregnancy. The answer is yes, they can! The reason that ovulation tests can act as a pregnancy test kind of is that the hormone LH that ovulation tests detect is molecularly similar to hCG the pregnancy hormone that pregnancy tests detect. Pregnancy tests are more reliable. Get diet and wellness tips to help your kids stay healthy and happy.
