Oh of course it's normal hon, have you had a look in the preg after long term ttc threads?
I spent my entire 3rd preg petrified I would lose her (for different reasons), and it really helped to chat with the ladies who felt the same - go introduce yourself, I'm sure you will feel a little better to know you aren't the only one...

Good luck, I'll keep my eye out for you in the birth announcements in about 9 months!
