I am wondering if to contact my doctor ...

I am 19 weeks pregnant and have been feeling my baby moving for the past week, some days she doesn’t move very much which makes me very nervous.

I previously had a miscarriage and whenever i am leading up to a scan I get anxious ... I have one in a week and I am beginning already to panic what is going to happen, is there going to be no heart beat, why isn’t she kicking as much.

Anyone else feel like this or should I try and go and seek some medical advice? x
