I always had very regular menstrual cycles my whole life, with little to no cramps, bloating, or moodiness, and
this was so even after having 3 kids and breastfeeding
. That is, until I went on the depo
. I only went as long as two doses, the first shot, then another 3 months later. After the first shot, I still had normal periods, then the 4th month (upon receiving the second shot) I no longer bled.
