Feeling blah all day?

Jessica • Just married, next on the check list... Babies!!
I am 11 weeks and 4 days and everyday from 8 weekish and on I've felt just blah. Not so much nauseous like I wanna throw up, but just off. Like I lay down cause I'm  tired but not, hungry but not, nauseous but not. I just don't feel myself.  It's kinda of annoying cause I can't explain it to anyone let alone myself. It lasts the majority of the day. If feels like I'm hung over, where you feel sick but nothing really helps or sounds good. I'm actually starting to think is it just me making myself "feel pregnant". Has anyone else experienced this?
