nope, i never felt wind at any time other than pregnancy, i guess its because as your uterus enlarges there is less space for other internal organs. if its fluttery bubbly feelings close to surface of skin, then it does feel similar to when the baby moves, but is still probably wind.
how many weeks are you?
you can work out how high your womb is in relation to your belly button, which will give you an idea of whether it may be baby or not, if its close to your belly button and you're only 3 months, then its wind...
on other hand, its all part of being pregnant so celebrate it if its making you feel good!
