This is also my third baby
Ihave felt it twice this week it's for sure not gas and it's low where the baby is... I'm 11 weeks too... I have been thinking I'm crazy
If this is your first, you might, but its unlikely. Air bubbles and the first flutterings of the baby are often confused because they feel so similar. First time mothers will generally start to feel movement from 16 weeks up, depending on the position of th placenta. (but don't be alarmed if it takes longer to feel baby. Some take as long as 24 weeks before they feel anything) a lot plays into it, such as body shape, weight, and position of baby and placenta. If this is your second or more, then its possible you could be, though even some second or third pregnancies don't feel it till later on as well.
