Maybe you had a cyst on your ovary and it burst. That can be really quite painful

Well i've been having a few pains here and there for the last 3 months so it could possibly be non-sex related at all...Worrisome perhaps?

I had exactly the same type pains after sex and just shrugged them off but then they got that painfull I never wanted sexand it wasnt until I researched my symptoms and got a chlamydia test online to try and rule things out,yet it was positive and I had been with the same partner for 4 years.So we both had to be treated.
And I know you used a condom but it can be contracted orally to.
Maybe go to your gp and mention your symptoms bcos it could also be pelvic inflammtory disease(pid). :d

The pains have stopped now but I have to rule out std because we hadn't had oral sex until after these pains has occured. They only lasted a few days but still I wonder what it may be. And as I mentioned I haven't had cramps since I started the pill back in october and yet they are slightly and faintly there. Maybe i'm just paying more attention to these things now that i'm active again
