heartbroken

hi girls, so my boyfriend of two years upped and left me yesterday, as hes found someone else. he left me before in November for someone and i dont know why i took him back. this is so out of the blue, im 10 weeks pregnant and our relationship has been fine if not perfect. hes blocked me on everything possible so i cant contact him and now im not sure what to do or if im going to be able to have this baby on my own:( heartbroken x
