So i felt a random bleeding outburst happen on my lightest day of my period. the blood was heavy, dark and what looked like a clot. Within less than 1min the blood was that heavy it had already bled through my underwear and track pants. My bestfriend believes it was a miscarriage but ive had two in the past and they weren't like this. There was no pain just sheer surprise. My period was also quite late 1.5months. I have regular periods. HELP
