I am a mother of 3, 6yo, 5yo, and a 4yo. All vaginal deliveries. No issues. I will be turning 40yo this year. I m not on any type of birthcontrol, my husband had a vasectomy. The question: I started my period a week ago Thursday, today is Saturday and I m still finding pink when I wipe. It smells a little different than the normal period and it has low viscosity. What could be causing this?
