Sue- have just come back in here and see you are pregnant! wonderful!!! congratulations

as for your query, you are so normal! I have been exactly the same with all my pregnancies. It's very stressful and hard to relax. I think the first trimester is a tough time..much of our innocence is robbed by this process and having experienced loss. Just try and find joy in each little milestone and think as positive as you can.
Hoping all is going really well
