first PP AF and supply

momtoalmost3

Apparently I am not one of the "lucky ones" who does not get AF while breastfeeding. I am 14 weeks PP and just got my first AF. My supply seems to have tanked also. Will it be just for a few days or do I have to work on increasing my supply? I wanted to BF for a year, so I am willing to do whatever I need to. With that said, I have no idea what to do to increase my supply, as just a few weeks ago I was worrying about my oversupply!
