Brief Answer: Possibly placenta will migrate Detailed Answer: Hi, Thanks for the query. According to your description I am thinking that you are mentioning about posterior placenta with inferior margin reaching the lower uterine segment. In early weeks of pregnancy sometimes placental margin can reach the lower uterine segment. Usually with progression of pregnancy placenta will move upwards. This is called migration of placenta. For more details : WWW.WWWW.WW Unless placenta covers the cervical os or approaches the cervical os, no need to worry. Regular followup checkups and ultrasound examinations are needed. Hope I have answered your query. I will be available to answer followup queries. If you are satisfied with the answer, please give your review at the end of the discussion. Take care.

Brief Answer: Better to be careful Detailed Answer: Hi, As placenta is approaching the cervical os the possibility of migration is somewhat low. But we cannot completely rule out the possibility. Regular antenatal checkups and ultrasound examinations are needed to observe the placental position. You should avoid : - Strenuous activities like weight lifting -Intercourse -Journey etc. Be in rest as much as possible. If bleeding occurs consult gynecologist immediately. Let your family members know your position. Be ready with details of your blood group, hemoglobin levels etc. Placenta presenting in the lower part of uterus may not cause a major problem always but better to be careful. If placenta migrates with progression of gestational age, no need to worry. Take care.
