Extreme Fatigue before Missed Period?

Hubby and I started TTC this month. I’m trying to be really calm about it because this could be a long road. I have a history of missing periods that we have not looked into why.

But my period is supposed to start in 6 days and I’ve had light cramping and extreme fatigue today and yesterday. I work from home so not having anywhere to go in the mornings has meant I slept for 11 hours the last 2 nights. I don’t feel sick or like I’m coming down with something I just feel tired, I have not overexerted myself either. I took a test, it was negative but its also too early.

Has anyone been this tired BEFORE their missed period?
