Ever since I went off the pill 3 years ago I have had periods that have fluctuated from 17 day cycles to 23 day cycles, the average has been 23 day cycles. Twice last year I actually had 28 day cycles. I have been hoping to become pregnant but was recently told by a friend that with cycles that were shorter then 28 days the egg was not given time to mature before it passed however since I was still having reqular periods that was a good sign and she suggested Clomid. Is there any other option besides taking Clomid? What is causing the shorter cycles? Is there anything that I can do to try to regulate them? I have never been pregnant however several years ago I donated eggs to a friend, who did get pregnant with twins however they had to keep me on the meds longer then normal to get viable eggs and at that I did not produce as many as I should have. Is there a connection between the prolonged response to the meds and the short cycles?
