Hello Dr, I am 33 weeks pregnant but my baby is in restricted growth, she is around 30 weeks which make a difference in aging especially that the AC measurement is little low. I was at hospital to monitor baby for 3 weeks and she is around 1,400 kg right now. I did an ultrasound last Tuesday and placenta age was grade 2 but after 2 days I did another ultrasound and the age was 3. What is the reason of that? because my placenta reach age 3 when I was 37-38 with my first baby so I did a c-section. For now, I did a Doppler and everything was normal but I am so afraid from delivering early. So, my Dr decide to do doppler and NST twice a week but can the placenta change to grade 2? what can I do to keep the baby at least to 36 weeks?
