So my doctor prescribed me provera for 10 days to get my period after I stopped BC. I took it and got my period about 4 days later. On CD10 I started using OPK's to check for ovulation and on CD13 got a smiley face (peak day). Just wondering if anyone got regular periods after taking provera once. Not sure if I should expect AF soon (since according to OPK I did ovulate) or do I have to take provera again to start it.
