movements 👶🏼

Last night I went to the maternity assessment unit due to my little girl not moving much (35 weeks + 1 day) 
They put me on the monitor for 30-45minutes till the machine said 'criteria met' and then had to go and see a doctor about the results.
The results came back good and they were happy with my little girls heartbeat and movements but they want to send me for a growth scan early next week? 
Also they tested my urine and I have white cells in my wee?
Nothing to worry about right? Has anything like this happened to you?
