I only breastfed my son for 3 days and he's been formula fed. I went back on contraception 2 weeks after he was born (nuvaring, I was on it before I had my son) anyways I'm 8 months pp and I still haven't had my period. I've mentioned it several times to my doctor and even the nurse but they keep saying I'm fine and it's normal... my partners starting to get concerned about it especially as we want to start trying again this year. do you think I should go to another doctor about it? how long did it take non BF moms cycles to return? I was regular every 28 days on the dot until I had my son!
