Hi ladies, I'm 18w and I've felt odd little flutters here and there for a couple of weeks like bubbles popping, 2 occasions ive rolls. Tonight was totally different. I had just eaten dinner and laid down, I felt a bit of pressure near my belly button and looked at it and my belly started moving in waves. It did it every so often for around 10 mins, it was the strangest feeling, could that be baby or gas? Would gas move your belly like that? I am showing a lot and belly was hard. I'm just feeling lots of big bubbles popping now. I can't wait to feel full kicks so I know it's the baby for sure.
