Unprotected sex or the pill?!

Unprotected sex or the pill?

I'm on the pill and I had unprotected sex a couple weeks ago. It was with someone new and it was quite rough. I was quite sore after having sex and a little bit of blood was coming out in my discharge. But two days after having sex i forgot to take a pill. The next day i remembered and took it but i then came on my period that day. I had my period for about 5 days and then it stopped (it stopped about 5 days ago) (also, i wasn't even due on, i was in the middle of my packet of pills)
I took my last pill yesterday and then started getting a bit of blood in my discharge again.

Do you think this is all due to having un-protected sex and i might of caught at STD, or could it just be because i missed one of my pills? (i've never, ever miss one before!)

2 weeks ago
Oh, i'm so pregnant even though i've been bleeding.. Yeah..

You know what - I can't believe the number of sanctimonious, judgemental idiots that have answered your question. Have none of you ever made a mistake?! I'm sure this poor girl KNOWS the consequences of having unprotected sex without you lot up there on your high horses throwing in your tuppence worth! The question was not "Please make a judgement on my sex life?", was it?!

To answer the question - the bleeding could be purely down to your cycle being a bit messed up because of the missed pills, or also maybe some damage after rough sex. It might not be a bad idea to have tests done for STIs if only to put your mind at rest.

Don't beat yourself up about one mistake, just do what it takes to make sure you're okay from now on :)
