okay guys so im 9 weeks pp i got my first period on the 7/20-7/25 i still have yet to get my second im only a day late and was reading that it can be normal but usually with women who are breastfeeding and i havent breastfed for like a month now so i dont know whether to be worried or not.. can anyone reassure me that this can be normal?
