It's fine until it gets uncomfortable. your body will let you know when to stop. it'll hurt and you won't want to lay on it lol.

Because Now When I Lay On My Stomach I Feel Like I Can't Breathe So idk if I'm Hurting The Baby lol

I do the same thing as @kirstenxoxo

I lay on my stomach with my knee propped up so I'm not laying directly on it. more like on the side. I'll be 33 weeks Saturday

I'm 23 weeks and 4 day's and I do occasionally.

I was told not to sleep on stomache , but everyone is different , I slept best on my stomache before pregnancy but now since I can't I will not do it until I have him ! @cynthiaa

I did till I was 3 months.. not best thing but if it doesn't hurt go ahead

That's what the doctors say but you can't believe everything I got my best sleep on my stomach
