Pregnant and toddler acting up

Anyone else having toddler tantrums to the max? I can’t take it anymore, it’s driving me absolutely nuts. My daughter went from well behaved to constantly whining and crying. I lost my cool this week and have yelled at her twice this week and feel like an awful mom. Super frustrated because nothing I do to redirect her or stop her whining/crying seems to be working. I know they say being pregnant makes them act up but this is an entire other level of acting up right now. Even my husband is starting to lose it and he’s one of the most patient people I know. 😐
