If you are pregnant, your hCG levels will be much higher than normal and an ovulation test may inaccurately detect this and read it as a high LH value. This is not to say that ovulation tests can substitute for a pregnancy test — pregnancy tests are much more accurate. How ovulation tests work An ovulation test is a test that lets you predict when you are going to ovulate. How do the hormones LH and hCG differ? What does an ovulation test look like if you're pregnant?
Can I use ovulation tests to test for pregnancy? Read Next. This is the fertility window ovulation tests help you pinpoint. The good news is that sperm can live in your body for up to five days after entering the vagina.
By timing intercourse around your ovulation window, you can increase the likelihood that sperm will already be there to meet the egg when it drops. Luteal phase — Remember the follicle the egg busts out of to make it to the uterus? During the last two weeks of your cycle, the luteal phase, that follicle hangs out on the surface of your ovary. The corpus luteum only forms after ovulation, and its purpose is to release a mixture of hormones, mostly progesterone, after an egg has dropped.
These hormones encourage cellular growth to help keep the lining of the uterus the exact right thickness — around millimeters. Why is lining thickness so important? If your egg turns into an embryo, it will implant into the uterine lining. A thick lining helps an embryo develop and will eventually become the placenta, the protective sac that will hold your child as she grows in your womb. The thicker the lining is, the higher chance the egg will implant and result in a successful pregnancy.
If a fertilized egg implants into the uterine lining, your body will begin to produce hormones that the corpus luteum needs to sustain itself, such as human chorionic gonadotropin HCG. When you take a pregnancy test, HCG is the hormone the test looks for to confirm a pregnancy. Without the corpus luteum, there is no trigger for your body to produce the progesterone levels needed to maintain the uterus lining. The drop in progesterone causes the lining of the uterus to be discarded.
From there, the cycle starts again. Ovulation tests look for this LH surge in your urine sample. Ovulation tests can look similar to basic pregnancy tests.
An ovulation test kit tends to come with multiple test strips to help you seize your peak fertility opportunity when it strikes. While there are typical symptoms that may alert you when to take a pregnancy test, this is not the case for ovulation testing. However, because an egg only lives for hours after ovulation, it can help to have a solid understanding of your fertility window.
Ovulation occurs at the midpoint of your menstrual cycle, so about 2 weeks after the first day of your period.
Start ovulation testing 10 or 11 days after your period starts to make sure you give ample opportunity for your egg to be fertilized. In that case, start using the ovulation test days prior to the halfway point of your cycle. If your period lasts a week or more, start ovulation testing on day 10 and keep testing.
Having extra test strips around can help you pinpoint your fertile period. As for testing day timing, keep your pee in mind. Excess fluid in your urine can dilute your hormone levels. Here are a few tips to help you get the most accurate results from your ovulation test:.
