I'm 25 weeks pregnant and still do it
Yes dear it may harm ur baby,even i was doing the same but my dr.suggested me to lay straight or left side on ur bed.
No,it will not harm your baby. I'm 27 weeks and still sleep on my stomach with no problems. Doctor said baby will let you know if he/she is uncomfortable. Its true, if my baby isn't comfortable with the way I'm laying he moves around to let me know to switch positions.
I always slept on my stomach but don't find it comfortable now
