I went back for my six week check-up on Friday and when my Dr asked about birth control I told him we hadn't really thought about it since it took so long for me to get pregnant the first time. (Roughly six years). He said that since I'm breast feeding this is actually a form of birth control as long as I'm feeding or pumping every four hours during the day and don't go longer than six hours overnight. Does anyone else have any experience with this form of birth control or heard this from their doc?
