I did that and enjoyed every moment of it while I still didnt have a bump! I remember my doctor say it's completely safe, even when you have bump lol. your baby is well protected by the uterus and amniotic fluid, so if you lie on your stomach with a bump then you're the one who will ache cos the uterus will push into your back (spine) 😅😅😅
I did, and baby's fine. Stomach was still flat then, so it's ok
I did while i dont have bump😂 but def not advisable !
