Hi Doreen,
I'm so sorry this has been so hard and frustrating for you!
I have PMDS too and it does respond well to progesterone therapy. The uterus remains undeveloped without a big flood of estrogens so your HRT may have triggered its growth - and not it has no room left to grow within!
Do you ever have blood in your urine? If so, then you have at least one working ovary in there and that is your period. I've had them for years. And yes, every doctor will want to make their name by writing about you in a medical journal (sign). I always say no, just like I always say no to having my internal lady parts removed. Oh they'll try to scare you with words like cancer but they can't show you one study that proves having a uterus, fallopian tubes, an ovary or two, and a cervix will end up being cancerous!
From my experience, an MRI and a good radiologist reading it is what will give you the most accurate reading on your body and what makes it special and amazing!
I hope this helps!
