I think this is very weird. I am in perimenopause and have not had my period for 9 months. I am on day 14 and on Day 12, I got my period. It is lighter than what I had been experiencing and at first I thought maybe it was just spotting, but nope, definitely, menstrating. I am pretty disappointed since I now have to start over with my 12 months of not menstrating. Has this happened to anyone else?
