I had unprotected sex 3 days in a row right before my June period was due.. but he has a hard time finishing so idk if he ejaculated or not. I was on birth control but also had a sinus infection so I was taking a z pack. A couple days later a got what I thought was my June period but now my July period wasn't actually a period. I normally have bright red blood and a constant flow for 2-3 days and then brown blood for at least 2 days after. But this "period" was spotting and mostly light brown, wearing only a panty liner and I had one day of red blood. I took a Preg test and it says neg. I would be 7 days late on my period but idk what to think.
