FTM feeling baby move at 16 weeks?

I am 16 weeks and 2 days pregnant. At 16 weeks exactly I felt a little worm like movement at the front of my belly. And today I felt a little rolling feeling after drinking a little bit of iced coffee. Is it really possible to be feeling my baby move this soon?! I know they say it is, but most first time mom's don't feel it for a few more weeks. I am in disbelief but so overjoyed if this is what it is! When did you feel your first baby move?
