Stomach Sleeping

So my 6 month old daughter can roll over back to front, front to back and wants to sleep on her stomach at night. I hate that she wants to do this and am scared and worried about her sleeping. Up untill now she has been sleeping in her bassinet next to me but since she wants to roll over and is out growing it, she is now sleeping in her crib. My husband and I started sleeping in the nursery as well just with the transition, but I just can't seem to leave her in there all by herself and go back to my room. We have a monitor, but again, she has been sleeping by my side for six months and I'm having withdrawals. Am I over worrying? Is the monitor good enough? Should I go back to my room? What if she doesn't have her head turned all the way to the side? 😣😬😟🥺 Advice please....
