ANYBODY? I NEED ADVICE!!

I am 14weeks and 4days pregnant with my very first baby. I am wondering if it's possible that I can feel her movements yet? I think I have felt them, I felt more like gas bubbles but came in sort of a rythem than gas.... It was slightly different. I am a very slim woman to begin with and I want to be sure that it's the baby that I'm feeling and not indigestion problems lol. any other first time mommy's felt the baby move at 14 weeks? I know second time mom's can feel it as early as 13 weeks, but it says for first time mom's you might not feel it until around 16 to 20 weeks. Any opinions??
