Hi, I need some advice I have been diagnosed with PCOS for the past 10 years so I was having irregular periods since my first period. I took an internal ultrasound which resulted with having cysts and a blood test confirming that I have a hormonal imbalance so I have been having irregular periods since then. I didn't have a period since July 2010 therefore I visit a gynecologist. He took a pregnancy test which was negative and also did a physical test which was negative. He put me on a Provera course to bring down my period. I also started "Serophene" fertility tablets on the 2nd day of my menstrual cycle, The last day of the period was December 27. I am also taking Metformin and Folic Acid on a regular basis. I am having sex regular since I am trying to get pregnant. For the past week I have been having heavy boobs in addition to sore nipples and abdominal pains. Can you advise me on what could be the cause of this? Am I pregnant since I am also getting nausea?
