Thanks for your query. It seems you are having POST-ABORTAL irregular cycles, it could be anovulatory also. As you mentioned your present cycles are regular but only problem is of excess duartion, hence I suggest you not to worry because for me it looks like a ovulatory cycles. if you are too anxious to get pregnant I suggest you go for Ovulation Induction
I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow ups.
Wish you good health.
