@Charl okay thank you so much and thank you😁
Is it bradwell? If so they've always booked it there & then after my scan. I would highly reccomend getting a private scan at 16 weeks though as they aren't allowed to write it down at the hospital
I'm sure that they normally book it at the time of the first scan unless they have no appointments available then they send a letter, just ask when you go. Congratulations 🎉
