Those who MC 3/4+ times..

As
For those who had a MC 3-4 or more times, did you ever get pregnant and bring to term? Did you get pregnant naturally? What was causing the MCs?  I'm 24, had 4 MCs and still waiting for a BFP.. Not sure why I can't keep a baby. 3 of my MCs were chemical and this last was blighted. I feel my body wasn't made to bear children or maybe I have retarded eggs or something. I'm so fed up
