Hello doctor, I have irregular periods but not pcod, hence my doctor has given me norm p and norm e to bring my periods on track...my last period came on 28 july and ended on 1 august...this was my first time having sex , I did it on 6th august with condom...as this was first time only penis tip went in, again we did it on 31st august this time the penis fully went in , he was wearing condom as well as we used pull out method , he didn't ejaculate inside me and neither the condom break or tear. But I was very stressed out and I took the medicines norm e and norm p for 3 days...ie from 4th September to 6th September and i got my periods on 10th sept but  the blood in starting was dark brown in colour, the flow was also light. Maybe this was because of the medicines. Hence please let me know there is possibility of pregnancy or not ?
