stomach sleeping

Apryl • 🇨🇻🇵🇷👭🦄🍀
so im currently 8 weeks almost 9 and im trying to get myself used to the "side sleeping" but sometimes i find myself going to lay on my belly, and im scared in the night if i fall into a deep sleep and i sleep on my belly if it will harm my baby? i really miss sleeping on my belly. and also i get this yucky taste in my mouth i try brushing my teeth and mouth wash but it doesnt go away anyone else get that symptom?
