I just got my first PP period a few days ago. I was sort of depressed for some reason. I think it was just because I heard that breastfeeding usually makes it so your period doesn't come back for a while. I felt like maybe I was failing at breastfeeding...I don't know.
I've been to afraid to try a tampon so far though. The first day or two were pretty heavy, but just a tad bit heavier than my normal periods before baby.
I guess this just means that it will be a lot easier to tell when the best time would be to NOT have sex, since I'm not on any kind of birth control (I don't agree with it). :)
