I have irregular periods. Sometime none for years. Had a M/C in 2005, at 20 weeks. . LAST month I was given Provera to start my period. Sept 1 was my first day to have my period. After that I took CLOMID from day 5-9. The last day I took clomid was on the 9th. A week later I was having bad cramps. For 2 days now I have been having sore nipples. Are sore nipple an early sign of pregancy? I will need to wait for another week to take a pregnancy test right?
