Pregnancy brain and hormones taking over

Y’all, I’m in my 11th week and the nausea has subsided but new perks have shown up. Today I had an ob appointment but even though it was in my schedule and I told my husband the right time, I for some reason all day thought it was a different time and totally missed it. When I realized I had missed it I felt like the worst mother and wanted to cry and hide in bed. None of this is in character and I don’t like it.
