Hi Ladies! I hope you don't mind me coming here to ask a question. I have a friend who has a 10 week old, her first baby. She is exclusively breastfeeding and has recently started spotting, sometimes very heavy. She has never had spotting before, even before pregnancy. She would just start her period. She's not had any changes in the nursing schedule, no solid foods have been introduced, and not had any trouble with breastfeeding. She wasn't expecting a period, or any breakthrough bleeding while bf'ing. Is this normal? Is it possible to start af so soon and while bf'ing?
