I have irregular periods, sometimes none for years. Had a period by Provera on 9-1. Took clomid 5-9. The last day I took it was on the 9th of sept. a week later felt bad cramps. 9-21, 9-22 and present, my nipples are SORE. Its gonna be the end of the month soon. Does SORE nipple mean pregnancy?? or is it still side effects from clomid?
