I was orginally on Depo-Provera for 1 1/2 years (never had a period), switched to Seasonale (major nausea), then switched to Tri-Sprintec (my chest got huge on this pill), and then to
Kariva (was great!). I was on
Kariva for 10 months. I never took the placebo week, so I never had a 'period'. However, if and when I missed a pill or took it a little late, I always had spotting for a day or two.
