I'm 19 weeks on Thursday so I'm almost there lol.
I did around 21 weeks. Like Jessbabe said, it looks like they're trying to get out already! And they're really hard kicks, too.
I started seeing my belly move at 25 weeks.. it looks like baby is trying to get out! Lol..
U soon will.if you lay on your back u can see all the action of the baby moving lol and if u don't, hold your breath for a few seconds then let go he or she will start moving.
