PZ I took the MAP while bf DD2 I gave her EBM I had stashed for 2 days and pumped and dumped. It did drop my supply for about 3-4 days but it came back fine once the drug was out my system and Dd was back at the boob. I think it was somewhere between 4 and 6 months. The pharmacist said I could BF while taking it but it would be in my milk and as I had heaps of EBM I used it

I found I had constant spotting with the mini pill so we used condoms and then had a problem with a condom coming off. I'm unlucky as AF came back at about 2 months after birth even while exclusively bf both girls

Good luck PZ
