2 vessel cord and baby in 2nd percentile??? HELP

At my 20 week anatomy scan my baby was measuring in the 26th percentile, it wasn't a concern for me or my doctor. At 27 weeks my belly was measuring 25 CM, my doctor wasn't concerned about it but she wanted to get a growth scan just for precautions, she said anything less than the 10th percentile is a concern. I am now 31 weeks and I found out my baby is in the 2nd percentile and I have a two vessel cord. They're sending me to a specialist to get everything checked again and I'll be having scans every week. Any mamas out there with similar problems? Will I have to deliver early? Need some advice/reassurance. Also, I'm starting to get morning sickness again and idk if that's normal either.... help 😖
