58, endometrial atrophy

I have endometrial atrophy, Dr put me on a hormone starts with a M, for 2 weeks, a week later after finishing the drug I'm bleeding again with cramps, nausea when eating...  Said that I may have break through bleeding but I'm miserable.  No fibroid, polyps, just thinning.  I'm on an estrogen/progestrone treatment...  Help

Have no idea what an "M" means?

I think she can't say the name brand on here?

May that's it. But I and many others have posted brand names on the posts.  I just thought from her post she couldn't remember the name of the stuff she was taking.  

Ah ok gotcha. Maybe she can clarify

I cannot remember the name of the drug! I called the Dr. office but the Dr. wasn' in Friday, hopefully they will call tomorrow.  Has anyone of you gone through this?
