Trying for baby after abortion

I had an abortion (pill form) in February ..3 years ago...it was a very traumatic experience... I was 18 at the time.. but as of August 2017 my boyfriend and I ( I'm now 21 ) have been trying for a baby...every time we have sex he cums inside me.. so about 7 months of trying with no success ..has anyone else had this issue? im afraid that the pill may have messed up my chances of getting pregnant again..
