Weaning

I was hoping to get some advice on weaning. My daughter is 2 years 4 months old and she still nursing for bed and nap time, I'm 18 weeks pregnant and it's just getting more and more painful to nurse. My husband is deployed right now and so it'll be just me trying to wean her. I was truly hoping she would self wean, but I see no end in sight and I can't handle the pain anymore.. please help 😩 she isn't a huge fan of other types of milk either..
