Good day. I have been diagnosed with pcos about 7 years ago. I was put on ginette,androcur and metformin. Within two months of using meds i fell pregnant. My son is now 5 years old. I was using petogen shot after until last month. I am put back on ginette 28 and metformin 500mg. I had an irregular period, then spottiness and then gone. Now i dont have appetite, feeling nausea all the time,esp.in the morning,tender breast and constantly tired. What could this be?
