Hello doctor, I am 17th week pregnant. I had scanning 4 days ago (since had brown discharge like clots) and found minimal subchronic hemmarage and low lying placenta and baby's is fine. So for SCH doc prescribed me celin 500 mg twice daily for 15 days and trapic tab thrice daily for 7 days and duvadulin 10 mg twice half tablet for 10 days. Please let me know why these medicines are provided. And also is it safe to take celin tab as I read too much vitamin c tablet may cause miscarriage. I am completely Stressed of these complications, since at 8th week I had laparotomy because of ovarian torsion. So requesting your guidance.
