Hello

I am 24 and had intercourse for the first time with my boyfriend ( me being the virgin). We were protected the entire time with condoms. After the first time i immediately bled on the toilet afterwards. I thought it might be the hymn but it followed with 7 day regular menstrual bleeding. On day three of bleeding we had protected sex again. It has been 15 days since intercourse and im nervous because i have frequent urination and bowl movements lately along with a cold...early signs of pregnancy. I am also experiencing more sticky discharge and mild cramping. My body adjusting to sex, ovulation, or possibility of pregnancy? I have no other symptoms. Please comment
