I had gone to my doctor after ttc for a year. All my tests came back normal and he said im healthy. I am overweight 5'3" 200lbs. My periods are normal but my bleeding has changed from heavy flow 2 days medium flow 2 days and light the last day to medium flow 2-3 days and light flow the rest. I have extreme exhaustion around my period for 1-2 days or up to 3 weeks and the longest run of it is 3 months in a row. I have tried to lose weight and get down to 180-190 and peak and again have extreme exhaustion.

My sister in law has PCOS and after talking to her she thinks I might have a mild form of it. What do you guys think?
