I can feel for you, Shelley...

I really can.

I wish I could help. I had alot of problems in my late 40's.
This was estrogen dominance.

My holdout was also ablation, but the doctor had me try
progestins for the last 10 days of the month, and that worked.
I then entered menopause with less stress. And after 2 yrs I could drop the progestin drugs (I used Provera, and then Aygestin because Aygestin was gentler). I do not have endo however, so your issues are more complex.

I was working midnights and that ruined me royally. I finally switched back to normal working times, and that helped too.
I had terrible heavy bleeding and short months.

I hope you find out what is going on. Don't forget to check out what you are eating..that gas/bloating can come from food intolerances. I am doing Beano now with all vegetables and also Lactaid milk and lactaid tablets with other dairy. These are really helping me. Also I am reacting to fructose big time since I had that sorbitol incident..so going sugar free has stopped bloating too. I cannot sleep when I have GI discomfort, either, and this makes everything worse!
