Impossible to sleep comfortably

Im now in third trim, 33 weeks, with a big heavy bump. Why is it getting harder to sleep 😭😭😭 the tummy always feel very very uncomfortable, heavy, suffocating, makes you feel restless and sometimes even crampy. I have tried putting small pillow to support my below, also doesnt works. I really miss having a long comfortable sleep 😭 see my husband sleep everynight like wah so shiok. I always end up falling asleep multiple times and work and sometimes feel like taking mc the next day. And people telling me to get as much as sleep as possible before baby comes when i can barely even sleep now (‘: Kind of envy ladies who have small bump throught their pregnancy.
