Progesterone only BC

Since I'm breastfeeding I decided to use progesterone only BC so I don't have to worry about my supply. I do not want any kind of implant (iud or implanon) and I'm AWFUL about remembering the pill so I went with the Depo shot. (I know there's non hormonal options but I don't trust them as much).

My problem is that I've been on my period for over a week! Anyone use the mini pill and have the same issue? I really don't want to go on it but if it means not bleeding this much, I'll deal with it.
