my nurse said, with provera, you should bleed within the time frame equivalent to how long you took it - so i was on it three days and should have bled within 3 days of coming off it (i didn't, but i'm a freakish case). i was also on double and triple doses at different times. according to DH, the side effects didn't get any worse as far as he could tell - i wasn't any nastier on the triple dose lol.
