I felt a flutter at 15+4, but never had it again. I felt the baby kick at 19+6 (Saturday), but no kicks since. It's because I never felt a second flutter that I'm asking this, but I felt vibrations in my lower belly at various times of the day. They lasted about 10 minutes at a time. I assume this is flutters again, but I'm not sure. I thought flutters were supposed to come and go in seconds; not be there for so long at a time! Has anyone had this?
