I've felt baby move, but nothing more than LITTLE thumps and flutters. Sometimes they are such small movements that if I wasn't perfectly still I would certainly miss it. I'm kinda getting a little worried. And there are times that several days go by without feeling anything at all. I'm pretty sure that I was feeling quite a bit by this time with my other pregnancies. Anybody else in the same boat? Do you think I should be concerned?
