I agree... its the baby..

i felt this one for the first time at 15 weeks and 1d... so its def possible..
But i agree with brittanie.. DONT under any circumstances stress about not feeling the baby move again.. or consistently, until you are like in your 20s... I still dont feel this little one move around on a regular basis yet!
I went all day until about 10:30 at night with out feeling movement just a couple days ago! NORMAL
