14 and Pregnant?!

So I spent the week at my boyfriend's house last week, from Friday the 8th until Sunday the 17th, and we had sex (unprotected each time) everyday vigorously and multiple times a day until I left, the only day he actually came inside of me was a little bit Wednesday and all of the way Sunday morning. In the past he's gotten two girls pregnant but they both miscarried, he thought it may have been because he's sterile or something. (Hes 19, 20 in September).

I've been incredibly sleepy lately, I've had white discharge and slight cramping. I'll wait until my next period is due to take a test, but what are the chances I'm pregnant do you think?? I'm worried, but I would keep the child. Please don't judge.
