Energy!!

Donielle🎀 • Campbell baby due August 2017
I need energy I just have absolutely none!! I need energy I have a one year old son and I'm pregnant with my second I'm a stay at home mom at the moment. And I honestly just want to lay in the bed all day but I know I can't I'm just so tired and weak! Can I take something for energy vitamins or something or do I have to just wait till it pass?
