Well...........something doesn't sound right to me. Depo is pretty effective. Ask her for a print out of the ultra sound photo. If you are seeing hands and feet....it ain't yours.
I doubt a doctor will talk to you on the phone about her medical issues. The best way is for you to attend an appointment with her so you can ask your own questions. It was worth the 3.5 hr drive to get laid......won't your peace of mind be worth it too?
Eat....you need your strength. You won't due yourself any good in a hospital too.
