Can pregnancy happen after having unprotected sex?
Patient: I don t keep up with my menstrual cycle because it s irregular but I thinks it s about 30 days. My last period started on September 12 and lasted 4-5 days. I had sex for the first time on October 4, unprotected but he didn t finish. Could I be pregnant? Doctor: Hi,Precum may enter into vagina unknowingly before ejaculation and it contain sufficient sperm concentration that cause pregnancy if sex was done in fertile phase of period. You got last period on 12th September, did sex on 4th October. So you did sex in the safe period of cycle if we consider 30 day of cycle. Ovulation will occur at 27th or 28th September and it will live only for 12 to 24 hours. But you did sex after ovulation so no chance of pregnancy. But you told you have irregular cycle. So if it has sometime long period like 35 days or more than pregnancy is possible. In this case you can take I pill with in 72 hours of pill to prevent unwanted pregnancy. Avoid stress, take healthy diet and drink plenty of water. Use safe sex practice like condom in future to prevent unwanted pregnancy. Hope this may help you. Contact further if follow up needed.
