I would suggest a repeat scan in an institute or medical College with good Radiology department or a scan with a fetal medicine expert, please find out one near you. A more detailed scan can give a good decision when to take the baby out. And nothing to worry as you are already 33 plus weeks, in good hands especially in institutes with good protocols, even 28 week babies can come out quite well.

Kept away from stress, meditate which can make a difference to to yourself and your baby. Take good healthy diet and your supplements too
