please help (update)

I have been having pain in my abdomen and occasionally on my right side of my abdomen. I have sex frequently but I always use condoms and have gotten a little bit of cum on the outer lip of my vagina once about a month ago but I wiped it off straight away and made sure it didn't go in my vagina and. washed my hands and vagina afterwards. My period is due on 4 days and I'm having white discharge. I have no idea what it could be. Please help!!

Update: I went to the doctor and he did a urine test. He said there's no sign of an infection and that there's a little bit of blood in my urine. He also tested for pregnancy and that came back negative. My period was supposed to start today and it hasn't. He said if my period doesn't start within a week I'm supposed to test again. He said that if it isn't pregnancy it could possibly be an ovarian cyst or an infection in my fallopian tubes. The pain in my side comes and goes.
