I have a spotting everyday for a month( this is literally the first time I've ever had spotting in my life). I went to my doctor 3 weeks ago and was put on Provera for 2 weeks. Still haven't started my period(first day of last period was 12/8) an no sign of it. I was diagnosed with PCOS last February and have surgery to have endo lasered in April. I've been having back pain, pelvic pain off and on for over a month. About 2 weeks before this happened I saw my primary because I thought I have a uti or bladder infection (again never had either) frequent trips to the bathroom trouble emptying my bladded but it resolved very shortly after on its own. Tomorrow I go in for an ultrasound and a follow up to get my results. I am nervous as there is a higher risk of cancer. I am hoping it's nothing.. My husband have been TTC for almost 3 years and were hoping my endo surgery would resolve or issue.. But we are still holding onto hope.
