Ok, so my lmp was Feb.5. Dr gave me 10mg of Provera to take for 5 days. I finished my last dose April 25 & still no AF. I talked to my doc today & he wants me to take it again, this time for 10 days. I had a horrible headache the whole 5 days last time. Has anyone had to take 2 doses to get their period? I'm just afraid I'm going to feel like crap for 10 more days & still have no period. Should I take it? UGH!
