So frustrated...

Question: how do you other mommas deal with people making comments & “advice” about your pregnancy that are negative? For example, I was walking down the hall with my hand on my belly (actually telling someone how hungry I was) & a girl came up to me who barely knows me & said “you’re not pregnant enough to be walking like that already” HOW RUDE. Or people saying well if you’re uncomfortable now then you haven’t seen anything yet or saying you’re too early to be feeling certain things? How do you keep from telling them to just shutup?? I don’t want to be rude but I’m feeling like I will never be “pregnant enough” for people to stop undermining my pregnancy. This is my pregnancy and every pregnancy is different! I don’t feel like other people should be telling me how I should feel or even walk!
