Every time after sex i notice blood come. I am married since 11 years. The blood is very little amount. And. It continue 5 hours maximum. My general Physician done a pap test . It came normal. But i heard that before pap test i can not do intercourse. But the day my sample was taken i had sex before.is that correct if i di sex before the test abnormal cell may mask. For that reason the result came normal? I always use condom. For what reason the blood can come.
