i'm sorry to hear that monika...
the problem with your situation is that all it takes is one sperm to inpregnate you. don't freak out about it though, let's talk about where you are in your cycle. maybe there's not too much to worry about.
when did you start/finish your last period?
also, not to be critical or judgemental in any way, but do you have a handle on how to avoid this situation in the future? we could possibly help you there as well.
the biggest single thing you can do though is not to get too worked up about it right now. let's just see what your cycle looks like and we'll help you figure this out.
