I have been on clomid for three cycles my cycles are getting shorter and shorter with today being day one of this cycle that has left me with a 21 day cycle when they are normally 28 to 29 days is this normal if so when should i be ovulating ?

Discuss with Doc: Part of being prescribed Clomid (clomiphene) is the education that comes with it. Besides being taught the risk factors & side effects, you should have also been shown how to assess for ovulation, timing of intercourse, & when to take your pills. This is combined with ultrasound evaluation of the endometrium, follicles, & you shouldn't leave the office without a better game plan. See an rei if failed 3 cycles.
