So I finished my 11 DAY period on Tuesday, had sex on Wednesday, and yesterday I got some light pink spotting which I thought could be implantation. As the day went on the blood got heavier and almost looked black, with clots, so I put a tampon in. Today the blood is bright red and heavy, I have cramps and I'm really emotional and scared. It can't be another period after just 3 days of the previous one stopping, please please please can somebody help me? 😭😭😭
