When I was 19, I was sexually active in a relationship and I became pregnant my then boyfriend's friend give me two types of pills,after I took the pills a few hours later I had severed cramps and lots of blood clotting and I did not went to a doctor because I wanted it to be a secret.. I did an abortion! I was so young and stupid... I'm now 28 and married to someone I love very dearly and we have been trying to get pregnant for over a year.
Is it possible that my past abortion can affect me in trying to get pregnant?

Have you seen a doctor? You should. He/She would be better able to answer this question. Give you a thorough check and go from there.
