I just had a period the 10th and it was a very heavy one. I got up and started to walk today and a HUGE gush of blood came running out!!! It soaked through a super tanpon within 20 minutes, SOAKED my panties & left the toilet looking like someone had murdered someone in it. I've had unprotected sex. Slight cramps, but no clots that I've seen. Help!! Idk what's going on?
