Movement

For the last few days, I've been feeling what I'm fairly certain is the baby moving.  I wasn't sure at first, and I still can't be positive that's what it is, but it's low, in the right spot, and just like a gentle nudging.  Like something very small kicking very hard but with some resistance, like say amniotic fluid and a spongy uterine lining.  Last night the baby kept it up for probably 30 minutes, every few minutes on and off giving me flutters.  It's exciting and gives me some comfort in these final few weeks before my ultrasound.
