I was always told that you don't feel the baby move (especially if this is your first pregnancy ?) until well after 20 weeks. It was 22 weeks + in my case (quite a bit after my anomaly scan) and all was fine. The anomaly scan is high-stakes for sure, but it's very special to see your little one on the screen for so long....
Good luck - I hope it is a window of enjoyment
After TTC for so long I know it is almost impossible to relax and enjoy being pregnant (at least it was for me)
