Anyone have any advice with irregular periods and clomid? I am new to clomid I took it once last August and had an ectopic pregnancy. Now my doctor gave it to me day 5-9 which was December 24 through the 28th. Was curious if anyone else has struggled with this. Not sure since I'm not getting a period if the clomid did not work. I thought I had a positive ovulation test. Also how long does your gyne make you wait until he gives your medication to start ur period and then the clomid? Have taken over a dozen pregnancy tests(all negative). Any advice will help thanks
