My Girlfriend and I and sex and....?

[anon01]

OK we had anal intercourse August 23 without protection (never doing that again) but i c*** anally also, mostly, while ejac. I slipped out. (We were sideways, and her legs were closed, i don't know if it's opened in that position but just giving detail, I'm kinda scared) Three days later, about that Thursday, her period came so now I'm still a little nervous to know if she's pregnant but she refuses to take a HPT, everytime I ask her to she says "no i'm not pregnant", "none got in" so about a month later her period came again and she had another one at the beginning of november, and she's starting to puke again so I wanted to know does it sound like it's period time, and does the beginning horrible scenario sound like she's pregnant and please no harsh answers...I've suffered enough :c
