Anyone with a similar experience?

I have just been to my 36 week appointment, I am currently (36+3). When my midwife measured my stomach she said I am measuring at 34.5cm and this is slightly small, only an increase of 1cm since my appointment 2 weeks ago. I have been asked to come back for another check next week and if my stomach is still measuring small then I will be sent for a scan.
Obviously now it's really worried me. Has anyone else ever had this?
