    Odd spotting
    Mel2day posted:
    I am 31 yrs old and have PCOS, I was seen by an endocrinologist in June to get further treatment for it and was put back on Metformin 500mg daily. In July I had abnormal spotting that was dark brown to black in color and it lasted for 2 1/2 weeks, then in August it came again this time for only 6 days, and only 2 1/2 weeks later on Sept 9 it started again. It is still going on making it 11 days now. I am not cramping or having any clots with this spotting which is highly unusual. My normal menstrual cycle goes from light with dark brown/black spotting to a heavier flow with bright red bleeding with clotting and then back with light darker only lasts 3 to 4 days.

    Does anyone have any idea what this may be? I did make an appt with my ob/gyn but won't see him until October.

    According to studies, Metformin can restore ovulations and normalize the menstrual cycle. Google "pubmed metformin menstrual cycle." Maybe the shortened cycles and longer periods are a temporary symptom of the Metformin attempting to do this. Did the endocrinologist mention anything about Metformin changing your cycles? You said you were "put back on Metformin." Was your previous use at the same dosage and did it affect your cycles then?

    Let us know what you find out and if your cycles normalize. I'm very curious about this as others may be too.

    The first two times that I was put on Metformin, after I was first diagnosed with PCOS it did in fact regulate my cycles (I did get pregnant after I started each time: started Metformin, had my first son, was put back on Metformin after having him, became pregnant with my second son). But when I was prescribed Metformin two additional times after having my second son, my body was too sensitive to the medication even at 500mg.

    So hear I am again giving it a go again this time through the endo, and now I am having all of this odd bleeding. I just had it start on Sept 9 and ended on 24th. Now yesterday it started again Oct 6th....had to reschedule my appt with the ob/gyn for Wed Oct 10th.....just really not sure what is going on never had this happen before.
