Did I overreact?

I’m usually quite collected and keep my cool. I’m over 40 weeks pregnant and exhausted!! My husband’s uncle has commented on my weight every single time I see him since I’ve been pregnant! It’s annoying to me. For example, he will tell me in front of others how I’ll never lose the weight I’ve gained during my pregnancy or he will comment on how much I eat...every time I see him! Unfortunately my husband was never around to hear it and I always let it go until today when I lost my cool. My husband and I were walking in the neighborhood. His uncle saw us and yelled “hi fattie” to me. I usually keep my cool when he comments on my weight but this time I didn’t. I was upset and said “could you stop commenting on my weight? It’s really rude especially to someone who is pregnant”. He immediately changed the subject and we all chit chat for a few minutes. My husband and I left and we didn’t talk about it and went on with our day. Did I overreact? I don’t want to come across as crazy
