Idk I need help if any of y’all girls can tell me what’s happening. So around like 4 weeks ago some family members came to visit so we decided to go to the beach. So the day they planed out to go I was scheduled to get my period therefore 3 days before it I took birth control pills for those 3 day. Also I’ve never been in birth control pills I just got them from my sister. Everything was normal I didn’t got my period into like a week later and it was normal. However now 4 weeks after taking the birth control pills for 3 days I had sex with my boyfriend. After sex I went to the restroom and had some bleeding not sure if is old blood or discharge. Is this normal can it be a sign that I’m pregnant or anything bad?
