I started medroxyprogesterone on the 2nd of December for 10 days to get my period back after being absent for a year. My period from this medication started on the 13th and ended on the 22nd of December not the 17th like glo says it did. I've been baby dancing since my period ended but I feel like glos chart is wrong at when I will ovulate next. What do you guys think. Is that to long to go before ovulating. Please help all my post are just being ignored
