It'll be right mate. I don't look pregnant in the slightest - just thicker around the middle. Have you been measuring your belly? I was pretty amazed to find that mine is 10cm bigger already, even though I have put on no weight. I don't know where it's coming from!

The movement might catch you when you least expect it - I hardly ever feel it when I'm lying down.
I am so sure it's all fine.... do try to relax
