People won't fight me now that i am pregnant?

i used to get in fights at clubs for fun with the other girls there. i just look at them and say "get away from my man" and then i push them and we'd fight. i dont even have a boyfriend lol. now that i am pregnant though, b-tches always be backing down cuz they see my baby bump. it doesnt matter how drunk i get, they always back down like chumps. how can i make people fight me even if i am pregnant?
