I've been sexually active with my boyfriend for few mos, and it's been few days, I'm having light cramping and spotting after sex.we are having regular sex few times a week. and I never had this problem with him before.They don't last for long, both cramping and spotting are gone after few minutes.cramping feels like the cramp you having when your period starts.. and spotting is not bad I just wipe it out and that's it.I don't feel any other pain at all other times, only cramping and spotting right after intercourse..I'm afraid if I got infection or something..or can it be that I'm pregnant??
You should go to your doctor and get checked out because it could be something simple or there could be a more serous problem . Theres many things it could be so you need to speak with a doctor, it is a good idea to start making a record of when your periods start and finish, when you have sex and when you have bleeding and pain . Take it along to the doctor with you it will help them to understand whats happening with you ok.
Hope that helps a little. x
