Baby Brain

I think I'm getting that "baby brain" thing where the pregnancy affects your thought processes and memory. I know it was affecting me a lot during the first trimester but then I felt like it got better. Now I'm starting to feel it again. I remember at my last job, my friend was pregnant and she'd be super tired and unmotivated to work. Then another girl here at this job was pregnant at one point and she was making tons of mistakes. I've heard that the pregnancy can make you forgetful and make it hard to focus. What am I supposed to do about it though? I'm doing the best I can and then they call me out on mistakes and simple but important things that slip my mind. It's probably just another strike against me in the eyes of my employer. I can't wait to have this baby and find a new job.
