So I got my first period on Thursday I think? Anyways, I didn't have any mestrual blood yesterday, so I assumed it was over, but then today, when I was going to the bathroom I noticed I had all this dark brown crusty stuff on my underwear? It didn't have a smell or anything, and I was wondering if it was just more menstrual blood or what... I only felt like tiny cramps nothing bad... so does anyone know what it is, and if it's bad? Please only serious answers, and thanks!
