When did extreme exhaustion set in for you?

Ha

I’m 32 weeks and yesterday I felt like I got hit by a bus of exhaustion. I ate 3 full meals and Franks tons of water and even had a nap and I could barely keep my eyes open through my birthday dinner! Then today I have a check up in the morning and I’m asleep in the car on the way home!! It’s been killing me so bad these last couple days!
