Feeling miserable

Hey everyone. I’m feeling miserable while pregnant and barely sleep and gets comfortable. I know got two months to go. Baby born March 30. But I can’t wait any longer. I also tired of doing the diabetes test at home for three times a day. ( blood work what number as long your under 120). No fun! And hard for me find foods to stay under. And I’m trying my best. I feel so weak not sure why. Unless not eat enough cuz of stupid test. What ya all think?
