I started my period for the 3rd time in 35 days. I started really worrying about it but talking with my husband, I realized that my periods do this in Sept/Oct then again in Dec and then now in the March/April months. Could the change of seasons do this? I also have Paragaurd IUD for 10 years. My periods have always been weird. When I was 17 (Im 32 now) I bled for almost 6 months. It was really light then on the usual cycle beginning day, it would be normal. Ive been stressed out too with all of my MH issues.
