Milk reduction?

Sam

Ok mamas I need some help. Last few days lo has eaten 5 oz more while I’m at work than normal and my supply has seemed to go down. I was producing twice the amount I was needing now I’m down to barely making it. The I my thing that has changed is I had Mirena put in last week. I need help I’m not ready to give up bfing. She’s fine while I’m home still normal, same amount of wet diapers and feeding the same.
