Fatigue is a killer

Sinora
I'm heading towards the end of my first trimester, I am 11 weeks 2 days today and my fatigue is worse now than it has been this whole trimester. In the beginning i wasn't tired at all. Over the last couple weeks it's been getting worse. I feel like I myself am a newborn baby. I'm awake for like 4-5 hrs at most and all of the sudden it just hits me n I get super tired. I don't even need to do anything. I'm so confused I thought it was supposed to get better and you were supposed to have more energy going into the second trimester???! Anybody else having this issue?
