Loss of appetite and fatigue....

Alyssa
I had a chemical miscarriage the 18th of this month, my dr put me on provera and I took it for ten days. My initial "period" only lasted 2 days and I've yet to start going on 5 days off the provera. I have zero appetite and have lost 20lbs since the 14th of April (it was needed but so quickly?!). I slept from 7pm last night to 8:30 am this morning minus the hour I was up due to storms. I'm still exhausted. I've tried eating even taking b12 and I'm still exhausted! What should I do??
