Can't help but to worry 😱😨

Melissa • Mummy to two coming 3 (due August) beautiful children.
So just out of an appointment with my midwife and after measuring my tummy she has said baby seems to be measuring on the small side and I will need to get a hospital appointment for a weeks time to check on baby. And will need kept a close eye on, she asked me to please not panic but I can't help it, I'm worried now something is going to go wrong with my baby girl. Any one else's baby measured small threw pregnancy and been ok?Â
