Where oh where has it gone?

Does any one else who is pregnant or has been pregnant out there feel like their brain is lost somewhere? I know I have gone through this before and each time it's just as annoying. I swear in the last few days, especially since we are on a new schedule, I have forgotten appointments that I made and usually NEVER forget, I have forgotten about promises to friends and to make calls that I swear I have made but haven't. I think I might be loosing it, my brain that is.
