Pregancy brain

Kr
So I'm 8 weeks pp, when abouts does my brain go back to normal? I just got up to get a bottle of water, walked back to bed and tucked myself in, only to get back up and go and get myself another bottle of water! When I came back, I put my newest bottle of water next to my unopened bottle I brought in my bedroom not 5 min ago lol. I do crap like this all day long. I know I already lost my damn mind a few months ago but when do I start gaining my mind back! My goodness!
