Holy crap, am I having braxton hicks??

So I'm just about 16 weeks. I actually didn't even think it's possible to get them this early but I read that in your first pregnancy you may start to get them from 16 weeks on and in your 2nd or however many you can feel them earlier. I actually didn't have any with my first baby, that I can recall anyways. This is super weird. Anyone else with me and experiencing them around 16 weeks?
