Baby movements freaking me out

Sarah • Older first time mom due in October.
I just started feeling the baby move a few days ago--I'm sure it's been moving before, but there was so much going on in my GI system that I'm sure I mistook it for gas or vomit. Now it feels like some serious thunking going on in there. It's kind of wigging me out! Like there's something trapped in there trying to get out. I hung up our one set of baby clothes in the living room to remind myself that it will be a cute baby that will wear adorable clothes, but still...anyone else a little freaked by all the banging around in there?
