At my 30 weeks ultrasound, the ultrasonologist told me that I had a grade 2-3 placenta since they spotted some calcification. The doctor did a doppler test and found that the circulation to the fetus was normal, but that there were some hiccups or notching on the left uterine vessel. I was asked to return in 2 weeks for another ultrasound and doppler, the results of which would determine if I needed to be referred to a perinatologist. The baby is thankfully growing well and is considered age-appropriate in size and weight, and my amniotic fluid levels are also normal.
I am not a smoker, drinker, do not have diabetes and have low blood pressure (always at 110/70), although I am 37 years old. This is my third pregnancy, with the second one ending in an early miscarriage. At 19 weeks, I was diagnosed with a low lying placenta resulting in some spotting, and was placed on bedrest. After 7 weeks, my placenta had moved up to a safe distance from my cervix and is now considered high lying.
My OB said that the appreciation of the ultrasonologist is also subjective, but best to be conservative. She is hopeful I will reach 38 or 39 weeks, but I have asked to schedule my CS (due to narrow pelvic bones) at 38 weeks.
Would you know when the placenta is supposed to turn grade 3? What does a grade 2-3 placenta mean? Are my chances of reaching full term good? And what can I do to help my placenta stay intact so the baby gets proper circulation and nutrients?
Many thanks for your advice and help!
