Hello ladies! Just took my last of 10 pills today of Provera.. Once AF comes I'm doing my first round of Clomid CD 3-7!! (also taking 1000mg a day of Metformin) so I was wondering how long after finishing your provera did it take for you AF to arrive? So anxious yet nervous to start my Clomid! Advice???? Success stories?? ANYTHING! Lol
