Please help me I'm so embarrassed!!

Michelle
My son is almost 4 months old and EBF. My right boob is huge compared to my left one. My husband pointed it out to me and now I am embarrassed and won't let him see or touch them. How do I get the left one bigger again. I've tried pumping to make it think it needs to make more milk, but I can sit for 30 minutes pumping and not get a single drop. Please help me!!!
