5 weeks pregnant and worried I've overdone it!?

Some people live extreme lives find out there pregnant and go on to have healthy babies. I on the other hand believe pregnancy to be an illness and this is not a good way of thinking. I am 15weeks today and found out when I was also 5 weeks gone and since then I was so scared to move incase the unthinkable happened........... It started taking over my life and up until a month ago I was even scared to work but I have gone on to lead a normal life and do the household duties and Im surviving. Just dont go to mad and always ask for help if you need it xxx congrats
