25+3 Weeks with my first. Struggling a bit

Em

I’m finding that I’m having bad back pain, which makes it a struggle for me to even get up off the couch or to hop out of the car. I also barely have any energy. Some nights I could barely get 4 hours sleep. Other nights I can wake up after a 12 hour sleep and still be so tired and have to have an afternoon nap. Anyone else having these problems?? Anyone have any helpful resources??

TIA
