Baby waking in night

Courtney
Frustrated first time mom here. 
My daughter is 6 months and loves to roll from stomach to get back but can't go the other way. Before she could roll over she would sleep on her side. Now I am getting up 6-9 times a night to her crying because she goes onto her stomach. 
Im used to sleeping all night long from 930-7,8. Great, I know. But I'm currently 14 weeks pregnant and am having a very hard time waking up so much. Any safe advice would be greatly appreciated.
