Weaning question

Alexa • Micah Tyler born 08/31/17 💙

I am weaning my 15 month old. I'm on day 4 of no breastfeeding at all. Before that we were down to once daily for a few months. However since I stopped my breasts are really full and starting to get uncomfortable. I read about hand expressing just enough to relieve fullness but nothing comes out. I don't know what to do. Is this normal? Will it eventually just unclog? My breasts feel lumpy and I can tell the glands are getting backed up. Helpppppp
