Jungleman gave you a great answer - can't really add anything to it. The length of the scan depends on how co-operative Flicker is feeling. Best of luck. Fingers crossed yor cervix is nice and long and Flicker is growing beautifully. Are you finding out the gender?
Thanks, I hope so too, we will find out but keeping it a secret, which is what we did with DD

Hi hun, our sonologist did the doppler stuff at each growth scan...........I would say it only takes a tiny little bit longer, it's pretty quick really, from memory (we weren't doing fetal doppler )

Good luck, I hope it all goes well. Will be following your progress!
Thanks Janie, ah yes it looks as though we have plenty of growth scans ahead of us and dopplers, but if it means we can keep Flicker inside for as long as possible then we will do it
