My periods are messed up. I spot so light I barely need a pantiliner for three days, bleed lightly for a day or two, then spot until the end of my eleven day periods. Most of the time I'm spotting it's so light nothing gets on my pantiliner. They used to be seven days and really heavy, but came every 19 to 90 days apart, they were SUPER irregular. I have PCOS. I had no periods for five years while on Mirena IUD, and went on the medication Metformin when I got the Mirena removed. Since then I've got periods that are 28 to 36 days apart and last eleven days. I think i probably don't have much of an endometrium building up each month and I think it means I'm not fertile. Oh, and I'm 35 next month. TTC for baby #1 is currently on pause as I have to take medication for a few months that causes birth defects. Does anyone have insight on any of this? I'll see the Dr of course, but I'm just doing research first.
