Pregnant?

Y'all please help me out here ! I'm 16 years old and new and my boyfriend had unprotected sex about 6 weeks ago. I'm on birth control pills and he didn't have enough time to ejaculate. But I know that you can get pregnant on precum. I've been having vaginal pains and a really thick white clumpy discharge. Kinda feels like a sponge that's damp. It has no smell. I know I'm really young but please no negative comments !! I'm really scared. Please somebody help me!!
