Hello doctors, My girlfriend is 22 years old and we had an unprotected sex last month ie on 24th of march. After having sex on that day after like 7/8 hours she got her regular periods. Still I did not took any chances on the next day that means 25th of march I gave her ipill and she had that. But this month its 6th of may and still there is no sign of having her regular periods. We two are lit bit worried. And if something happens what we have to do. Waiting for more than one week for her period is safe or should we go for a doctor? Please help please.
