when ever i have sex with my boyfriend i start to bleed. also when he hits a certin part in side me it causes me to blled more than just a little bit and it hurts and i get a pressure feeling. but for me it is through the whole month everyday justa little bit when im just doing normal everyday things. i also get sharp pains up my back and in my stomach and lower pelvic area. it sometimes feels like the pain is in my vaginal area. i have my periods every month like i am suppose to so im not pregnant but i am still worried. if anyone has any ideas what this could be please let me know. ? !
