It shld be ok if she turns herself. At this age, she would be able to adjust herself or cry if uncomfortable. My boy started to flip to his tummy when he's 2+ months and can only go into deep sleep when sleeping on his tummy till now at 6 months. If I were to turn him back, he'll wake up. Just make sure tt you put her down on her back if u were to put her in the cot. If she were to turn to her side, let her be and don't put anything ard her.
No it is not dangerous as long as there is nothing blocking her and also do keep a look out as some baby turn when they are sleeping some couldn't breathe
