If I have a dysfunctional bleeding from a d and c that I did 10weeks ago, how do I induuce ovulation?

Find the source. It's important to first find the source of the problem. Just taking medicine blindly to induce ovulation without finding out why the abnormal bleeding is happening in the first place is dangerous and senseless.
Few options. 1. D&c usually does not affect your ovulation. So just wait, you should ovulate natrually. 2. If your D&C was due to pcos with thickened endometrium, then you may need Clomid (clomiphene) to help you ovulation 3. If your D&C is after abortion, then you have to wait a month or two after your HCG level back to normal again. No treatment needed.
