Full breasts??

Mia🖤 • Mommy to my baby boy 1-13-2018💙👶🏻

I woke up this morning with my boobs super hard and full, I fed my son my right breast and now it’s a lot softer. My left however feels like a huge lump but it doesn’t hurt. What is this? Is it just my milk? Clogged duct? My milk flows good in both my breasts.

This is my first time breast feeding, I’m just trying to get familiar lol
