Oh yes, girl. Lol. I am 33 weeks with my 2nd pregnancy. With both of my pregnancies now, I have had major "prego brain". That's what me and my husband call it. :)
It's pretty common, actually. Not all women have it, but quite a few do. 2 things that help me:
1) Lists. I can't go grocery shopping without one anymore or I forget at least 3 items. It's nice to just have it there right in front of you, too. Less stress.
2) Saying things out loud.
