Screaming during 3rd trimester

Hi mummies.. I am at my 3rd trimester juggling between work and taking care of an active toddler at home. I have no family support. And taking care of an active toddler is really mentally and physically tiring. I find myself screaming all the time and I get worried that it will affect baby thereafter… anyone scream and had a healthy baby? I need some assurance to keep going… thank you.
