I have PCOS, my doctor recently prescribed metformin (not diabetic) for the PCOS. I'm also on metro-gel for an odor and dian 35 to regulate my cycle. I have been bleeding on & off since i started the metformin and the dian 35, I inserted the metro-gel 2 nights and on the 3rd day I started passing out some thick brown objects which looks a lot like squeezed chicken liver. These nasty things have been exiting my vagina for 3 days now, I'm a bit freak so if anyone can give me some input on my condition I would very much appreciate it.
