I am truly sad about my current situation and wondering who is the father. My boyfriend  and I always had unprotected sex for a while now I don't use any birth  control anymore. We got into a bad Argument and I had a one night stand. I wish I didn't  and I really regret it. I  don't  wish this upon anyone and its making my pregnancy horrible.

My last mentrusal cycle was started 08/28 not sure when was my last day.

I am 5 weeks and 4 days so far.

My last night stand was 9/11 and I was with my boyfriend 9/12 

I really appreciate the help and I need all the answers I can get, I can't ask anyone else and I am alone.

Is there a paternity test to find out who the father is?
