Pregnancy brain ain't too joke!

Since about week 8 of pregnancy I've been so scatter brained. I forgot to show up to my moms house when I had been planning to go over for 2 weeks. Completely spaced. Then today it hit an all time low. I intentionally put the keys to my car in the trunk because I thought I need them in the car to start it. Locked myself out of the car, out of the house, and out of the trunk 🙄 My husbands best friend had to come let me back in. At what point does your brain start to work again?
