funky hormones and irregular bleeding

quick medical background: I'm 35, have 3 children and have had two first-trimester miscarriages.  My periods, until a couple of years ago, have been regular as clockwork, although quite heavy.  Then, I started having irregular periods (two one month, one the next, none fore the next couple of months, etc.).  I developed cystic acne and multiple breast cysts.  My doctor said I had an enlarged uterus and that I was severely anemic (from all the bleeding). He thought it might be fibroids or endometriosis (my mom had both and needed a radical hysterectomy at 38).  He did a pelvic ultrasound and didn't see any sign of either (or any significant cysts), so he recommended a hysteroscopy and endometrial thermal ablation.  

After the ablation, I had light staining for more than six weeks.  The Dr. gave me 10 days of progesterone to get it under control.  Seven days later, I had an actual period for a day or two.  That was June 19th.  Since then, it seems I'm not ovulating.  

My endocronologist is confused.  She's done weekly blood tests for more that a month.  I have low estrogen and progesterone, and my FSH is higher than my LH (which means it's not polycystic ovarian syndrome).  I had an MRI of my pituitary gland, and it looks normal, and my thyroid tests, testosterone, and other hormone levels are normal.  They also did a dietetic panel which was also normal. And am now chronically constipated.

A few days ago, I started lightly spotting (so who knows, maybe I finally ovulated), and I have a horrendous backache.  Help!!! Does anyone know what this is?

You poor kid.  Makes me wonder WHY they do the ablation, without darn well getting to the CAUSES, know what I mean?  Obviously (well in my opinion) the ablation isn't going to solve your hormone imbalance issues.  At least your endocrinologist is trying!  I did think that it would be PCOS.  Have they suggested putting you on the Pill for a few months trial?  And you have had your ovaries thoroughly checked, as in at least a transvag ultrasound?
Good luck to you, hope someone here has some answers....

I just saw your other post about the hyster.  In case your doctor didn't tell you, leaving in the ovaries is NOT the ideal solution that they imply it is.  Ovaries do not function as well without the uterus.... in fact, many women are sooner thrown into sugerical menopause anyway, even with the ovaries.  The blood supply to them is damaged or removed.  Try reading Screaming to be Heard by Dr Elizabeth Vliet.  
I hope you find some answers.
