Anyone else having sleeping/Snoring problems?

Im just over 21 weeks and have been really struggling with sleep. I feel as though i roll around and change position more than i actually sleep. My husband told me today that he was listening too me last night and i that i was breathing very heavy and kept snoring really loud and then waking up and changing position. I didn't have this problem pre pregnancy as far as I'm aware.

Is anyone experiencing this, or should i be concerned? I would absolutely love a good night's sleep.
