While I'm at work, (I'm maintance at Walmart) so I'm running around, have a poop ton of tasks to get done .. Usually by the end of my shift I'm rushing to get done sweeping the whole store. That's when I have to stop cause I honestly feel like I'm fixing to fall down and faint. I do stay very hydrated cause honestly the store feels terribly hot to me and I'm doing a lot of running around trying to get my tasks done. I eat at all of my breaks at at lunch so it's not like I'm hungry.. Works getting really hard on me but I need to work till I go into labor.. Just today I had to catch myself from falling somehow, kind of like when you drift off to sleep you jump up really fast cause you realize you're falling asleep ? Idk. It's weird. Just need to know what's causing it.. I'm 35.5 weeks pregnant
