Any suggestions would be great

Ok I have nursed my twins for the past 23 months but I’m 18 weeks pregnant so we started weaning. They have officially been off the boob for the past 11 days now but my boobs are killing me. Now I’ve done hot showers and gentle massages but nothing is working. Tonight I tried to just hand express some of the milk to take the pressure off but it’s sooo thick it looks like colostrum but I don’t think my milk should convert that soon. It also taste different as well. My question is would you continue to express it or just leave it alone?
