Does being pregnant give you a pass to be rude?

All of my friend’s 3 pregnancies my friend was totally rude. Calling people ugly, ignorant, morons, etc. Then she would say “sorry I’m just pregnant.” I had never been pregnant before but I figured that maybe pregnant woman just get hormonal. One time she yelled at a lady from a local sandwich place we have because they sold the last sandwich and the “preggo didn’t get to eat”. She demanded she last customer give her the sandwich and they did. She didn’t even eat half of it... Now that I’m pregnant I feel irritated sometimes but I do feel like I can at least control my emotions. Is it different for everyone? Can you really not control your emotions?
