Braxton Hicks VS. Big Movements

earthspirit

So just wondering.....I'm 29 weeks and have heard a lot of talk about Braxton Hicks at this point. I don't think I have had any yet however my lil' peanut has been very active and making much bigger/stronger movements lately....which I would assume is to be expected as he gets bigger and stronger. There have been a few times in the last 2-3 days where there are these huge movements right under my navel and I'm wondering if I could be mistaking BH for just huge baby movements? I tend to think I would definitely know the difference but I'm just not sure. I've hear the whole belly tightens when it is BH...is that true?!
