Pregnancy brain.

OK I feel like this is the only place I can come and talk about this. I had a doctor appointment today. I was up at 5:55 for no reason and could not fall back asleep. I didn't even have to be up until 7:10. So anyways I was suppose to get my glucose test today but I'm only 26 weeks so I thought that was weird. Well they told me they miscalculated when they scheduled it so it's rescheduled. All they did was a usual check up, I got to hear baby's heart beat and a million questions. Well when I left I forgot to check out and schedule my next appointment. I felt so stupid and honestly was almost crying on my break, I called up there and they were really nice and understanding and scheduled my next appointment and just reminded me to stop by the front desk when I leave. I seriously was so embarrassed and overwhelmed, I felt like everyone at work would laugh at me if I told them what I did. Has anyone else had really bad pregnancy brain lately?
