Has this happened to anyone else?? Started the mini pill at 6 months pp, started spotting a few days into the pack and by 5 days in I had a full blown period. Never had one up until now so I'm sure it's the pill that caused it. I've also noticed a dip in supply, but I'm not sure if that's due to the pill, having my period (hoping it will go back up once it's done) or some other factor. If my supply keeps dipping I'm definitely ditching all forms of hormonal bc until I'm done breastfeeding. What was your experience with the mini pill??
