New to this and wouldn't normally post but very worried! This is my first pregnancy and Had my first ultrasound at 7 weeks as I wanted to confirm pregnancy. They confirmed it and saw a small heart beating and said I was measuring at 7 weeks When I finally went to my 12 week scan they said I was only measuring at 10 week 4 days. They said to come back 2 weeks lAter. Went back today for when they thought I would be 12 weeks, couldn't get a clear image but said I was only measuring at 11 weeks and 4 days. They seemed concerned as the baby has only grown a small bit and said even though it was in an awkward position, it should be bigger. Have referred me to kings college in London tomorrow. Very worried. Has anyone got any advice or been in similar situations??? Thanks
