This is due to how pregnancy and ovulation tests work. A pregnancy test detects the presence of human chorionic gonadotropin hCG. Both of these LH and hCG are known as glycoproteins, and share similar protein components. If you have enough LH or hCG in your urine, your ovulation predictor kit may read either as a positive. Wait until you miss your period to reduce any false negatives from testing too early.
Otherwise, know that the body is wonderful and complicated. A prolonged positive OPK is likely nothing to worry about. For more posts about getting pregnant, follow The Fertility Institute blog today. What does a positive OPK mean?
Why do I keep getting a positive OPK? What causes false positives? Ovulation tests work much like pregnancy tests. These predictor kits measure the level of hormones in the urine to let women know when they are ovulating.
Ovulation tests specifically measure the amount of the luteinizing hormone, or LH. LH is a hormone released by the pituitary gland.
Then, about halfway through the cycle, there is a surge in LH levels. When an ovulation test result is positive, it means that LH levels are high, and ovulation should occur within the next 24 to 36 hours. As soon as an ovulation test is positive, it is a good time for our Houston patients to start trying to conceive. An egg should be released within one to three days of the positive ovulation test.
Once an egg is released, it is viable, or fertile, for around 24 hours. Considering the possible window of ovulation, and the lifespan of male sperm, couples should have their best chance to conceive in the first two to three days following a positive ovulation test. Most experts suggest that couples have sex two to three times during this timeframe to increase the likelihood of conception.
Unfortunately, ovulation tests can be costly. The good news is that women do not need to test as frequently as they may think. If a woman has a regular cycle, she can start testing a few days before the midpoint of her cycle. Testing in the morning is best.
