I am 20 weeks pregnant and today I go for my anatomy ultrasound. I am excited but at the same time I am really nervous.

This is pregnancy number three for me but everything about it has been different. I havent felt the baby move but a few times and im not even positive thats what i felt. For the past few months I have had this overwhelming feeling like something was going to go wrong. Im scared ill go for my appointment and they wont find a heartbeat. I dont know why I feel like this but it really sucks! I know all mtb go through this a little bit but this is to the point i almost dont want to go to the doctor.
