I am a Type 1 diabetic. I have conceived via IVF I had a frozen embryo transfer. Yesterday I was 7weeks and 3days pregnant and I had my ultrasound scan, but CRL was 6mm. The nurse has really scared me as she said the baby should have been 9mm in length. There was a heartbeat but she said next week it may not be there and booked me for another scan. I know I should not worry, but I cannot help it. Has anyone got any advice or has anyone been in my situation?
