Okay so I recently lost my virginity to my bf but I bleed with is common but I didnt bleed a little , but I also didn’t bleed a lot it was okay I was fine but when we did it the second time I bleed a lot I got light headed and  I went to the er asap but they said nothing was wrong but I bleed so much that I went though 2 pairs or pants and if I were to sit down I can jus feel more and more blood coming out but after a while of laying down at the er I was fine I didn’t bleed that much but I’m scared to do it s third time because what if it happens again if anyone knows what’s wrong or has been though this please help
