Hey I've been with my boyfriend for 7 months and we've had unprotected intercourse plenty of times I've already been tested for std and I was clear back in august then all of sudden on Saturday it started to be painful for him to go inside me and got worse Sunday night to where I didn't want him to stop and not continue so he could finish because it was hurting bad and I was also starting to get pains in my abdomen that felt like cramps and getting pains in my tummy so I thought I was pregnant but I did have a period this month but it was a day late and somewhat light and lasted shortly than it always does so I took a pregnancy test today and I was not pregnant then all of sudden when I just went to the bathroom to go pee it hurt bad to go pee and I was bleeding while I was peeing and when I wiped it was light pink. So what do you think is wrong with me? Please help! I'm only 20 and I'm scared!
