Might be pregnant

I might be pregnant and my bf left me yesterday saying he needes some time "things" were going to fast like the whole baby thing. And now his friend shows me a picture of him the same day laying with another girl in his bed😔 i can't help it but i cried so hard all day than knowing my grandmas anniversary death was yesterday to. I keep on texting him saying pls talk to me but he wont talk to me. He was trying to get me happy for what he did and kept texting me than he heard about me not wanting too take him back so now he wont text me saying it really hurt him but he has hurt me to. What should i do? I'm scared i might be pregnant, i'm 2 weeks late, i have sore boobs with veins on them, i have white discharge coming out, i been having slight cramps for about 3 weeks now.
