I was more than a week late for my period and had sex with my boyfriend, the condom fell off inside me because it wasn't on all the way and we had to pull it out. I can't tell if I'm pregnant or not because I started my period the next day. My vagina is swollen and I can't stop itching on the inside and outside of my vaginal area, it has been going on for a few days. I am in extreme pain especially when I take out and put in tampons. please help
