Ovarian Cyst since October

I've had pain in my lower right abdomen since Oct. 25.  Ultrasound confirmed an ovarian cyst on Nov. 8.  Went for another ultrasound Dec. 20.  Got a call from OB stating "The situation has resolved itself."  Still had pain until Dec 24 when I got a terribly painful period.  Seemed as if it was gone until Jan 16 when the pain returned and has been continuing.  Feel like my OB doesn't want to bother with me.  Could it be same cyst? New cyst?  Should I get a new OB? Any suggestions welcome.  Especially if you have been through this!  Thanks in advance!
