I was wondering if I could still be pregnant? I been having the pregnancy symptoms. Me and my man had sex on late Friday night into Saturday morning. Plus I already had my period back in June the first week and stopped on the 14 of June. But when I woke up this afternoon I am bleeding super heavy and feel so nauseous and sore body parts. So I am wondering if I can still be pregnant or take I go ahead take a test now or wait?
