I have always have very irregular periods. With the birth control pills, I regulate my period, but after I decided 2 years ago to get pregnant, my periods stopped. I took provera and didn't work, then I took for another month birth control pills and I had a Period. Then I had norethindrone, another kind of progesterone and It has been working to regulate my periods but I don't ovulate. So I took 50 mg of clomid for 1 cycle and it didn't make me ovulte. It is so frustating!!!!. I have had all kinds of exams and it seems everything is ok. has anybody has a similar problem. I don't understand why medication doesn't work for me!!!!,
