Second trimester!

Anyone else having trouble transitioning into the second trimester? I've been struggling with fatigue this whole pregnancy so far but the past few days have been unreal. I'm not nauseous but I'm not hungry either and I have to force myself to drink. Over the weekend I had a migraine that made me so sick I ended up in the ER for fluids and I just feel like I haven't felt the same since. Had my 12 week appointment yesterday and everything looks great, baby was jumping all over the place and heart rate was 168 so no concerns about the health. I just feel like I was hit by a truck, I've been in bed all day. 😅
