I am 15 almost 16. Me and my boyfriend do have sex quite a bit.(uses condon every single time.) and I am on a 28 day cycle. I was suppost to start this last Saturday that passed. And I didn't.. The next day on Sunday I went to my boyfriends house and we did have sex.(with a condom). Went home Sunday night, didn't start my period. Monday passed by and I still didn't start. Finally Yesterday came by and I still didn't start my period.. But when I went to the bathroom I had a clear discharge. Like raw egg. Clear and a little white. No smell. No itch.. Then the whole day Tuesday I took 5 pee's and the discharge slowed down and now stopped as of today. (Wednesday) I didn't have any discharge at all today. But I have a pain on my left bottom area. And I was thinking... Well that's a sign of ovulating and I did have a white discharge. And I was wondering if I ovulated late and that's why my period is late... Or am I pregnant and the white discharge is a sign of it...

I believe I'm 4 days late of period. 3 days in I had clear/white discharge.

3-4 days isn't late. If you don't get your period in two weeks then you're late. That is when you should be getting a home pregnancy test.

Condoms, while effective, still have a failure rate, and if he's not using it correctly it could result in a pregnancy and unwanted if I am not mistaken. Have you talked to your doctor about birth control to help this matter?
