Hello Dr. I am 18 weeks pregnant. 15 days back I had bleeding. My placenta is touching internal os. My doc had advised me to take proluton 250 injection once a week till 30 weeks. And also asked to take duphaston 10mg. Plz note this is my 1st pregnancy without any abortion history. Plz advice if I really need to take this injection for so many weeks. Also I should take a bedrest..
