pregnancy brain is a downer

At ten weeks pregnant, I experienced for the first time "pregnancy brain" which is when you're pretty forgetful about things. I'm not sure how, but I lost a five pound bag of rice somewhere in my house. The thing is that I cooked with it yesterday, cleaned up afterwards and have no idea where I put it when I was cleaning up! Bags of rice just don't walk away! I was craving rice and chicken and I couldn't find it :( My husband swears he didn't throw it away or hide it from me to mess with me. I used to think pregnancy brain wasn't a thing until this happened. Has anyone else lost something they otherwise would never misplace?
