Scared of hurting the baby

Looking at pictures of embryos in the uterus they look so fragile and I'm really worried that I'm some how going to hurt it. Like how I sit, I feel like I have to sit down extra slowly and carefully. Sometimes I just fall back into my seat and then get scared I may have hurt it. I like to curl up on the sofa and I feel like that could hurt it. I feel like I have so sit up straight all the time. I'm worried about the way I sleep because I move around alot. If I bend over to get something. I'm soo paranoid it's unreal. People tell me to relax and that unless I had a bad accident or something there's absolutely nothing I can do that can hurt the baby from the outside. Is this true? How protected is the baby in there especially when it's so tiny?
