Updated! Growth scan because baby is small

Has anyone had this happen where your fundal height is consistently small so you have to get a growth scan, and then it turns out everything is fine? I'm a little bit worried as it's been slipping every measurement so started 1 week behind, then a week and a half behind and now she is 2 weeks behind, so I'm getting a growth scan to check she is doing okay 😓😓😓 I'm 34+6 measuring 33 hopefully she is okay and just a small baby

UPDATE: we got booked in for the scan in the same day, turns out baby girl is measuring perfectly in fact even a week larger! Supposedly she is weighing 6lb something but I know this is inaccurate 🥰🥰🥰🥰
