Could this be a sign?

Sammie

Just got a kitten last Friday. She's really sweet and even likes to play with my seventeen month old son. Whenever I'm laying down, she likes to lay on my stomach more than anywhere else. She was just doing it and I swear I felt flutters. Haven't gotten my BFP yet but I'm really hopeful for this month. We're going to take a break for awhile if it doesn't happen (taking a test tomorrow). Has anyone experienced something similar and gotten a BFP soon after?
