Is this rude?

I work in healthcare and I had two patients ask if I was pregnant today. I’m just starting to show at 25 weeks so it’s not like I’m huge yet but I feel like it’s kinda rude to ask people that. What if I wasn’t pregnant and just a little heavier? And am I going to have to deal with this the rest of pregnancy if it’s starting already?! Ugh people should keep their comments to themselves. Now I’m self conscious
