I am 8 weeks PP & have not started my period yet.  My doctor prescribed me my normal birth control pills.  I breastfed for 5 weeks and then switched to formula.  My husband has not finished inside of me but I took a pregnancy test just to be safe & it is negative. My question is, should I go ahead and start my birth control pill or should I wait for my first period to start? Any other ladies experiencing this? Thanks for the advice!
