Hi, quick question. I came in my girlfriend s anus about 2 week ago, and she was supposed to get her period 4 days ago. Now, she s 16 (as am I), so I assume it is still irregular. That being said, I m still slightly worried, because I m 16. In your experience, what are the chances that she could become pregnant from the semen possibly dripping into her vagina? Wouldn t it be incredibly unlikely? Thanks in advance.
