[|Human|] Hello Doctor, Me and my wife had unprotected sex yesterday (10th may) and i came inside her completely. She started her period last month on 19th. So is it a safe day? Also i want to know the effect of ipill if consumed after 72 hours or after like 5 days? If she is already pregnant (due to previous intercourses) what is the effect of ipill on the developing baby? Will it be normal. Thank you
[|AI|]  Hello, I have gone through your query and understood the concern. Ovulation occurs two weeks prior to the onset of the next menstrual period. Hence, if she has regular monthly cycles, she was in her safe period during the sexual intercourse. If this was the only act during this menstrual cycle and if she had a normal period during her previous cycle, she cannot be pregnant from a past act. Thus there is nothing to worry about the effect of the pill. The protection offered by the pill intake tapers from 98-99% just after the intercourse to 70% by five days. If she does not receive a period ten days after she is due, please get help. Take care.
