So had sex with my bf last month 3 times and aftwr each time i staryed bleeding. Bleeding would last for 5 days like a period... first 2 times with bad abdominal pain like he broke me on the inside... last time wasnt bad... but this period this month was like a murder scene blood everywhere... then it stopped then sat on toilet and and i felt it gush out. What could this mean? Filled toilet bowl
