I am really confused - will try and explain what is going on without being too lengthy.  I had diverticulitis a year ago and late last year started having pain in my lower left abdomen along with bleeding/spotting for 30 days.  My doctor did a CT scan, found no evidence of diverticulitis but did find a 4 cm cystic structure to left of the uterus and posterior to the dome of the bladder.  I went to my gynecologist and she did several tests, including a transvaginal ultrasound and noticed I had "one small cyst" - after dealing with the pain and bleeding for 2 more weeks, she did a D&C to stop bleeding.  She had tried hormones and after D&C tried bc pills.  One week later, I was still in a great deal of pain and it was getting worse (although it was intermittent rather than constant) so she did another transvaginal and found cyst had grown double the size and there was a second one, plus uterus was enlarged.  Did surgery to remove cyst.  I felt great for 3-4 weeks and then pain started up again (low left, occasional pulling pain on right, intense lower back pain, nausea, lightheadedness).  Dr. put me on low dose bc pills again but is hesitant to do anything further and wants me to wait for scheduled transvaginal the end of next week.In the meantime, I have started diary and have found pain is consistently happening 3-4 times an hour, getting worse and I haven't had a period since early December.  I am 49 years old and up until recently have never had a problem with either cysts or with my period (regular every 28 days).  Should I be concerned?  Suggestions?
