OB and U/S

We had our 2nd OB visit and 3rd U/S appointment this week.
It was so exciting. The babies actually look like babies now. They have long arms and legs, and fat bellies.
Baby A is is lying the lowest, and is more on my right side. Baby A was pretty quiet during the scan. It was just hanging out, resting on it's side.
Baby B is on the left and is higher up. This one seems to take after Joel. It was moving non-stop, flipping and squirming. The tech had to poke me in the belly to try and get it to cooperate with us so she could get the measurements.
They were looking wonderful. They had nice, strong heartbeats, and were measuring at 15w2days, and 15w5days.
I have another appointment next month along with an u/s, and then one the following month, with another u/s. Then we start having the appointments every two weeks.

I think I've been feeling the first movements. It wasn't like a kick or light movement. It felt like a big roll. I was laying in bed, and when I looked down at my belly and put my hands there, I noticed that my belly was completely lopsided. I think that Baby A had done a big flip over to Baby B's side of the womb. I called Joel into the room to show him how crooked my belly looked. It was quite funny, and really exciting. After a few minutes, there was another pressure shift and my tummy when back to normal. I think this is just the beginning of the acrobatics that are going to be occurring.
