I just ended my period Sunday and I know how my body works. So what I'm feeling right now I never feel. I'm still cramping and have been having really bad headaches the past few days. I've been feeling nauseous and peeing a lot. I'm not sure why my body is acting like this. I have read a few stories where girls still get their period and can be pregnant. What do you guys think! I need some advice or answers even thoughts. Please anything helps!!
