Rude or not?

I'm 33 weeks pregnant and my mom constantly is grabbing and rubbing my belly. It's becoming irritating. I just want to yell at her. Well today she grabbed my belly and said "I bet it's annoying when people grab your belly all the time." So I responded, "Yeah it is.. You're really the only one who does it." It was definitely passive aggressive I just wanted to tell her to stop with out full saying "don't touch me anymore. Was I being rude? 😂
