Zero lack of motivation

just me

So I am now 7 weeks pregnant, I work full time as a phlebotomist. I have an hour drive one way....

In the mornings I am exhausted at night I am irritable and exhausted. I lack no motivation to do anything..

Does anyone have any tips on how to get motivated to be active. I'd love to go walk on the treadmill at the gym, I'd like to do prenatal yoga at home... but finding the time is near impossible.

Example... today work from 5:45-2:15 so I wake up at 3:30 to get ready, leave at 4:45, get to work, then leave at 2:15 get home at 3:15 to clean. Then hubby gets home around 4:30 then we cook dinner then its 5. Then it's shower time, then bed.

I have no drive to do anything else. With my work, chores, and exhaustion. Help!
