Hi all, 3 months ago I had an unprotected sex with my girlfriend and since that time she has not got her periods. As she was saying that there is a little blood coming out but it’s not red its bit brownish red. So, is it her periods or is it implantation bleeding or period? She bleeds little bit and then it stops. I hope it’s not a symptom of pregnancy. Can some one tell me about it and what she needs to do at this point of time?
