How to tell the difference???

Lindsey • first time mommy to be

So I am 22 weeks today! And I'm waiting patiently (sort of) to feel my baby girl move! I think I might have felt something like a two pokes last Friday and then a little something last night in bed. But my husband said its probably just gas.

How can you tell the difference between the baby and gas?

FTM so would love advice!
