I’m currently waiting for my phone call - I had my 28 week appt yesterday and fundal measurement was on the 3rd percentile so also been referred for urgent growth scan. Try not to worry, the fundal measurements can often be pretty inaccurate so doesn’t mean for sure baby is smaller than they should be! I’d also just get in touch with midwife or ultrasound unit and follow up they should have you in the system with your hospital number
I’ve not had this happen but I’d give your midwife a call to say you’ve not heard anything. I honestly wouldn’t worry either. When they measure your bump it’s called fundal height and it’s really not accurate at all. Each midwife does this differently and regardless your bump size doesn’t actually reflect how big baby is x
