Pregnancy brain real?

I feel like i'm losing my mind! So im normally a very articulate person. I was an english literature major and now i find myself struggling to find the most basic words. It's really embarrassing. Im tripping over myself in conversation, i can't remember anything like where i put my purse, i'm putting things back in the wrong spot and not remembering. I don't remember this happening( at least not this early) with my other two. Ever since i hit the second trimester im stuck on dumb. I haven't been able to sleep more than 6 hours so maybe that's contributing? Anyone else dealing with this? I always thought it was mostly a myth.
