Completely normal how you are feeling. I had two m/c early on and even now @ 33 weeks I still get nervous when bubs hasn't moved much or for a while. I have a scan next week and even though bubs has moved a fair bit today, I am still very nervous cos I have these horrible thoughts that something will be or is wrong......... I think for me it is my way of protecting myself if there is a problem IYKWIM. Good luck for tommorrow, I am sure everything will be fine.......... keep us posted.
