NC for this.
I had unprotected sex twice (once at night and once in morning) and whilst it's unlikely I'm pregnant, I could be. It is with someone I am not in a relationship with and is very unlikely I ever would be.
If I am pregnant, AIBU to just terminate the pregnancy without telling him? I guess you could say we are friends (loosely) and have some mutual friends. I'm likely to spend time with him again in social settings.
