So normal. And let's hope those pregnancy hormones have something to do with how you are feeling.
Have a cup of tea and just think positively. Think about seeing tiny bubba on the screen. I was the same every scan as it was a scan where I found out twin had stopped growing, I had no idea that was happening. So I have to trick my mind I be super excited and don't let myself get scared, it's hard.

I'll be thinking of you.
