Provera newbie starting tonight

Mary

After being surprised my OBGYN prescribed me provera and femara on my second visit I’m finally starting the provera tonight. Had to delay to ensure I️ didn’t start withdrawal bleeding during thanksgiving when plans include skiing and hot springs! Anyone else set up with 5 days starting nowish? I️ plan to take at night but feel nervous about side effects - I’ve been medicine free so much of my life! Can anyone share experiences with side effects?
