Pregnant for 3 months, the lower margin of the placenta reaches the internal os of the cervix, what is the meaning?

Patient's question:

No

Doctor's answer:

Your condition does not fall under the category of threatened miscarriage, but you should also rest more. The placenta will move upwards as the uterus grows. It is recommended to have a follow-up ultrasound in two months to check the development of the fetus.
