The past week or so I've been feeling a lot down there, but it was quickly followed by gas.
So last night when I felt the tiny flutter I waited.. and nothing. I realized that my stomach didn't hurt and I didn't have gas at all. Then I felt the flutter a few more times. It was low on the left side, right where they picked up the heartbeat with the doppler. (I know this because she tried in the middle and on the right and nothing. It took her 10 minutes to find it because it was tucked down low on the left side.)
I'm not 100% sure... but I do think I felt the baby last night.
