Chances of conceving three years after abortion?

Patient: In 2008 i had an abortion, which was performed at a clinic and was done under sedation. I never had complications and got my period a month later on time ever since. In the same year i took morning after pills atleast 4 times.This year 2011 i have been trying to fall pregnant and it is not happening. Could the abortion and morning after pills have ruined my chances of ever conceiving?
