Enough dirty diapers?

La

My son will be two weeks this Saturday and I am worried whether or not he’s eating enough. For the past two days I have changed several wet diapers, but only one dirty diaper each day. Yesterday he had a dirty diaper In the evening. This morning he had a huge blowout that leaked out of his diaper, but nothing since. It seems like he’s hungry every 1-1.5 hours..so I put him to breast and he nurses at least 15 mins on one side (until he seems to get aggravated) and I will switch to the other for at least 20 mins. With him pooping only once each day the past two days (but having several wet diapers) is a sign of my milk supply decreasing? Anyone have a similar experience?
