I am 18 years old,sexualy active for 2 years now,and 3 days ago while i was having sex,during penetration i didnt feel any pain ,but after a few minutes it became unbearable..and I had to stay still for a couple of hours until it faded ..my period always comes on the 32nd or 34th day ,but now its late, my last period was on 22.5.2013.
This has happened a few times before,that my period comes late..i dont feel any pregnancy simptomes. and my boyfriend and me always use protection and we are careful. What should I do ? Is it possible that what happened two days ago could disrupted my period ?
