Abortion and Getting Pregnant Later

This is very personal for me but would like some other women's advice. I had an abortion when I was 22-23 yrs old. I was at full 12 weeks to have it done in my state. And it seems even after going off birth control that I can't seem to get pregnant...not even a scare of being pregnant. I'm about to be 32 in a few weeks. I was not using any protection, bc, condoms etc. with my last serious bf and still nothing.
