Thanks for your query,,
Third trimester brings a growth of the lower uterine segment, that is more than the growth of the placenta. For these reasons, while 5% of pregnancies are diagnosed with low lying placenta in second trimester ultrasounds will see 90% - 95% of them resolved by term . So a follow up ultrasound will be done to see the final position of placenta. However if it persists it may lead some risks as-
Complications for the baby include:
Problems for the baby, secondary to acute blood loss
Intrauterine growth restriction (IUGR
) due to poor placental perfusion
Increased incidence of congenital anomalies
Risks for the mother include:
Increased risk of postpartum hemorrhage
Increased risk placenta accreta
(Placenta accreta is where the placenta attaches directly to the uterine muscle.)
So take proper rest and be alert. If any bleeding occurs , contact your doctor immediately. If the baby is moving at present then you can presume that the baby is ok.Growth scans are needed to detect any growth retardation at the earliest.
Hope it helps you.
