How common is it to have a stillborn?

The only sign I can think of is less - none baby movements. Be sure to do your baby kick counts and make sure it's up there. If you notice the count is down don't be afraid to call you O.B. and let her know. They will do a Non-Stress Test also called a NST to check the babies heart rate and make sure everything is okay. Don't stress over this because you heard that someone that is the same amount of weeks as you had a still born. Everybody is different and things happen because GOD has a plan for everyone. Take it easy because your baby will feed off of your stress.
