I'm 21 weeks pregnant. The baby has been kicking occasionally for a few weeks, but today he's so active it's incredible. How active are your babies? I had my ultrasound last week so I know he's beech and that the movement I feel is kicking... Not sure if the frequency tonight is normal. Kicking several times a minute, perhaps once every 10 seconds or more??  I plan to call my doctor tomorrow, but wanted to see what you've all experienced.  I also had a few short pains in my pelvic area tonight, perhaps Braxton hicks?
