At least I think that's what I felt!!!!! I'll be 17 weeks tomorrow, and about 3am this morning i was woken up by this weird feeling almost like popcorn popping in my stomache! I got excited when it occured to me what it could be and then i couldn't really pay attention and fell back to sleep. This morning during a meeting at work I felt it again!!! I think it's really my baby flipping around! I'm so excited I just had to share!!!!!
