I have been on Camila mini pill for a year and breastfeeding my son 1-2 times per day. I have regular periods for a year lasting 2-3 days heavy and light for 1-2 more days. This week I started on Sunday, unusually heavy and that lasted for 5 days and the last 2 days lighter and the following Sunday barely anything. Well today I am bleeding like a normal flow period again, this is 8 days, never ever has this happened, ever and I have had periods since I was 13. What could this be?? :-(
