"Help" for Adenomyosis

Hi there!  My name is Lori Ann.  I am 31 years old, married, and have never been pregnant.  I was diagnosed - via a lap - two years ago with stage 3 endometriosis.  Most lesions were removed at that time, but I still continued to symptomatic (heavy, long, painful periods and significant daily pain).  I was put on Femara, then Lupron (for a total of 1 1/2 years post-surg).  There was no improvement and, to make matters worse, I fell into a very deep depression while on Lupron.  I was taken off of Lupron in February and had a Mirena IUD placed shortly thereafter.  Again, minimal improvements.  I had another lap/hysteroscopy done last month.  Most of the endometriosis had involuted and the only "significant" findings were ovarian adhesions and endometrial polyps.  It's been suggested that I have adenomyosis and that I should strongly consider having a hysterectomy.  I have a very rare coagulapathy (a polymorphism) and am on Lovenox, so I've now seemingly run out of treatment options, as I can't use traditional BC.  My main question is: Can adenomyosis alone cause infertility?  If there is a chance that I could get pregnant, I would postpone having a hysterectomy as long as I could.  I have such severe daily pain - taking alot of pain medications just to function "normally" - that I know I'll probably need to have my uterus removed at some time.  My husband and I would really like to have at least one child, although we've never really been told if that is a possibility or an impossibility.  I know that my situation is incredibly complex, but I would sooo appreciate any advice or guidance that you may have!  I could "hang in there" with the pain and terrible periods a bit longer if there is a chance that I could get pregnant someday.  I/we've had a hard time getting some straight opinions.  THANK YOU SO MUCH!  Blessings, Lori Ann
