Is this amount of pregnancy brain normal?

Ellen • Proud first time mama! My beautiful daughter, Roxie Marie, was born on April 23rd, 2016. I love my baby girl. :)
I'm 28w5d & this is the worst I have concentrating on anything in my life. I will be doing something & feel like I forget what's going on 5 seconds later. I don't know of this counts as pregnancy brain or a state of confusion that I should be worried about. Is anybody else having this? It's honestly frustrating.
