For the last 3 years I has on a high dose of injectable insulin. Went to my endo to get an insulin pump and as it turns out I am now back producing above normal levels of insulin. I was taken off of my insulin and put on Metformin 2000mg. Prior to this I had slightly heavy 7 day periods, regular predictable cycle. Now they are 14-16 days long, heavy and are very unpredictable. I am hoping that this will regulate and go back to my normal cycle very soon. I have a follow up in December. Any thoughts insight or suggestions? Please I am at my wits end! Thank you.
