Sleeping on stomach

Somebody tell my annoying boyfriend that I’m only 17 weeks & I can sleep on my stomach 😂 he’s so concerned it’s making my nerves bad, he’ll literally turn me on my side in the middle of my sleep if I’m on my stomach and everybody knows you’re not suppose to interrupt a pregnant woman’s sleep 😂 Are there really any risks of sleeping on my stomach so early?? He’s convinced I’m smushing our baby, I think I’m gonna mention it at our next appt so my OB can explain it better because I’ve told him time and time again and I don’t wanna be mean because I know he means well but sheesh I’m getting annoyed lol
