Measuring small

Went to my growth scan today 29 weeks and babies long bones are measuring behind. She is in the 8th percentile and Dr said she hasn’t grown so much since last scan 😞 her long bones are almost 2 weeks behind and her head is a week behind. Everything else seems to be 29 weeks. I am looking for words of encouragement and see if anyone has been through the same. From now on we are doing 2 appointments a week with Doppler to check is she is ok. Dr thinks it might be growth restriction and is keeping a close eyes on her.
