Sleeping Issues! 😟😩😥

I am 21 weeks pregnant and I am having to worst time getting sleep! It seems like nothing I do works. No matter how many pillows I use, different positions I try to sleep, hot shower or bath. I can not get comfortable enough to sleep! I'm also a nursing student, so with all my studies and clinicals going on, I need all the sleep I can get.. Is anyone else having this problem? Does anyone have any suggestions that may help?
