Why haven't I gotten pregnant? My bf cums inside me everytime we have sex but I squeeze it out.

See a doctor? If you want to conceive and you've been trying more than one year, it's time to see a fertility specialist or a good obg who works with fertility. I would not worry much about semen spilling after ejaculation, that's normal and likely not a problem at all.
Poor contraception. Be responsible. Use reliable contraception until ready to parent.
