Pregnancy is one such condition that can falsely indicate an LH surge because pregnancy hormone levels, known as hCG levels, are similar in structure to LH, and they bind to a common receptor.
Can LH levels detect pregnancy?
They’re not meant to detect pregnancy and a positive ovulation test does not mean you’re pregnant — that’s what we have home pregnancy tests for! However, you may have heard about some women using their ovulation tests as a pregnancy test.
Will ovulation test be positive if pregnant?
So theoretically, if you’re pregnant, and you use an ovulation test, you may get a positive result.

Pregnancy tests are more reliable.
What is LH test for pregnancy?
An ovulation home test is used by women. It helps determine the time in the menstrual cycle when getting pregnant is most likely. The test detects a rise in luteinizing hormone (LH) in the urine. A rise in this hormone signals the ovary to release the egg.
What happens to LH levels after fertilization?
Ordinarily, it’s secreted at very low levels throughout your menstrual cycle. But once a developing egg follicle reaches a certain size — usually around the midpoint of your cycle — LH secretion surges to really high levels. This hormone surge is what triggers ovulation about 24 to 36 hours later.
What will an ovulation test say if pregnant?
An ovulation test isn’t as sensitive as a pregnancy test, so it won’t pick up hCG as early as a pregnancy test will, and it requires higher levels of hCG to turn positive. In addition, there is no way to distinguish whether the test is detecting your LH or HCG levels.
Does 2 lines on an ovulation test mean im pregnant?
Unlike a pregnancy test, two lines alone is not a positive result since your body makes LH at low levels throughout your cycle. A result is only positive if the test line (T) is as dark or darker than the control line (C) line.

Can you ovulate while pregnant?
Ovulating during pregnancy happens so infrequently doctors haven’t been able to study why it may occur. While uterine abnormalities aren’t quite as uncommon, doctors typically see people with a divided or partially formed uterus, not two separate uteri. This condition, called didelphic uterus, is rare.
Does LH surge always mean ovulation?
A rise in LH levels in the blood can predict when the follicle (sac where the egg ripens) is ripe and ready for ovulation. Because LH is released in pulses or short bursts, the LH surge is not always found by a single blood or urine test.
