pregnancy after twins

Hey guys so this is my third child (fifth pregnancy). I have a daughter and after her twins. My question is does anyone know if you show sooner after twins? I swear it seems like my uterus is already peeking out from the bone and fundal height is halfway to the belly button! That's not supposed to happen until like week 12. So my question is do you know if you start showing sooner after having had a twin pregnancy?
