Early Baby/Growth Scan

Went in for a growth scan at 33+6 and baby boy is measuring 5lbs 15oz 37 weeks already. Doc used Doppler after ultrasound appointment and I was sent straight to hospital bc of his high heart rate. After evaluation of his heart he has intermittent fetal SVT on top me being 5cm dilated now & my due date is December 15.

I was given steroids in both legs to mature his lungs faster and put on bed rest. I have doctors appointments with both my obgyn for regular appointments and maternal fetal medicine for ultrasound monitoring of his heart (2 different places) every week for the rest of November.

Anyone going through anything similar?
