Mentrual cycles?
I had a regular spell the month I was on Nuvaring but I skipped the ring the subsequent month and haven't gotten my period.
Answers: It could clearly mess it up. It could also be stress too.
i dont reccomend birth control. because you will get soo used to have a lite short period, that when you eventually enjoy to stp using the pill your period will be conventional again and be a huge pain.
