I had my period on the 28th, it lasted 3 days. I had unprotected sex with my boyfriend, he pulled out before he cummed. 2 days later (Yesterday) I had pinkish blood come out when I wiped. I was in total confusion, wondering why I was bleeding when I just had my period, it later stopped that day. Than today I had nausea, and felt cold. I also have been having cramps most the day. So if anyone could help, I'd really appreciate it. Thinking I bleed cause I've been stressed out. But I don't think that would cause it. Thanks!
