Thanks for the query.

Usually grade lll placenta is expected after 37 weeks of gestation.
Grade lll placenta at early gestation indicates rapid aging of the placenta.
It can be seen in conditions like high maternal blood pressure, gestational diabetes etc.
As you are having history of blood pressure that can be one possible cause for this.
In these cases there is possibility for fetal growth retardation, decrease in amniotic fluid level etc.
But in your case though placenta is showing grade lll maturity, fetal weight, liquor and other parameters are normal.
So now you can continue the pregnancy with regular antenatal checkups and ultrasound examinations to monitor the growth of the baby.
Regular increase in the growth of the fetus and adequate liquor indicate that the placenta is working properly and supplying adequate nutrients to the fetus.
Along with this strict control of blood pressure, taking nutritious diet and adequate liquids are essential.
Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
Take care.

Dear Doc, Thankyou very much for your positive and quick revert.. It has relieved a lot of tension.
Would just require a bit of info :
How old is my baby at today date and by how many weeks a baby can live on his own before the full 9 month cycle if there is early delivery requirement.
Also is the Fetal Heart Rate 133bpm in normal range as earlier it used to be around 155-160 Approx.
How common is Grade lll placenta at early gestation? and till what time it can be continued. Thanks a lot.
Answered by Dr. Sree Gouri SR 3 hours later

As per your last menstrual period your gestational age by today is 33 weeks and 1 day.
Usually fetal lungs will mature by 32 weeks, so after that the fetus can live in the external environment. But good neonatal care is needed in this case.
Normal fetal heart rate ranges from 120 to 160 bpm.
From 30 to 32 weeks fetal heart rate decreases and by 36 to 37 weeks it will come to 130 to 140 range.
And also heart beat will vary from time to time. So it also depends on the baby movements at time of ultrasound etc.
Compared with normal pregnancies grade lll placenta is common in pregnancies with medical complications as I told before.
If the baby growth, liquor etc are normal and blood pressure is under control the pregnancy can be continued till term.
Wish you Good Health, If you are satisfied with my response please rate the answer after closing the discussion.
Take care.
