Labor pains, not pregnant!!!

Hello.  I'm a 36 year old, and it seems to all goes down hill from here.  Every 2-3 months on the day I start my cycle I get what I can only decribe to be labor pains!  (only one of my problems).  But it starts like I'm going  to be sick and throw-up.  From there its all labor pain syptoms (feel like I have to go to the bathroom, but can't, terrible back pain, and contractions so bad, my legs wont let me walk).
  I had a laparoscopy done to look for endometriosis and was told my female parts are heathly.  Three weeks later I had an MRI done and was told I have a large amount of fluid on uterus and cysts on both ovaries.  My ovaries feel sick most of the time.  I talked to the nurse about getting a cancer test (CA-125,BRCA1&2) done and she pretty much laughed and said Oh, honey..... and went on about the tests not being accurite.  Does anyone know of any other cancer tests?  Also in 2004, I was on clomithene citrate for fertility.  I cant seem to find any information on clomithene other than its a anti-estrogen...?...
  My breast have been so tender for the past 4 days (I have to wear a bra 24/7 or they feel like thier gonna pull off my body).  My cycle should start friday.  I'm worried.  Any suggestions????
