The result of ovulation test after ovulation is weakly positive, which does not indicate that a woman is pregnant after intercourse. Ovulation test paper cannot be used to determine whether a woman is pregnant after intercourse, but only to determine whether her ovaries have ovulated. A weak positive result from a morning pregnancy test or a pregnancy test may indicate pregnancy, but a weak positive result is only the result of a relatively short pregnancy test. If a man and a woman have sex after ovulation, the chances of conceiving after intercourse will be higher. If a woman conceives successfully after intercourse, she may also observe that her menstruation will be delayed. If you doubt the result of the test paper test, you can also go to the hospital to determine if you are pregnant by taking a blood test is more accurate.
