Has anyone else felt a calm and mellow pulsating movement? It's kind of like hiccups but definitely more quicker and gentle. Its not my pulse or myself breathing, its much quicker! I know my baby is head down and I feel in the middle of both of my hip bones. I googled it and it said baby is practicing breathing. It makes sense! Have you felt this yet too? Or does anyone have a different theory on what it may be?
