why cant i sleep😭

selena

27 weeks and im up at least every 2 hours to pee or drink or just swap positions and its driving me INSANE

i never experienced this with my other 2 and its killing me. i also work full time midnights and rarely get more than 4 or 5 hours of sleep total a day! this cant be healthy? should i consider going off of work early? any ideas on how i could get myself to sleep longer stretches?
