Hello, I am 17 weeks and 3 days pregnant as of today. I had an ultrasound at the end of 3 months. I am pregnant with twins. The report says that placenta for one baby is fine. However, it is low lying for another baby. The report says that the twins are dichorionic diamniotic. For Fetus B, the placenta is along the posterior wall, reaching up to internal os and covering it. Please let me know if this is a cause of worry. I am currently on bed rest. What other restrictions are required to be taken? Pls let me know. Thank you.
