Hello Doctor, This is soumya. I was diagnosed with Subchorionic Hemorrhage in my 11 week and it was 26×21 mm, so as per the advice of the gynecologist I took progesterone, antibiotics and vitamin and again had an NT and Dual Marker at 13 weeks which showed negative but the SCH has been changed to 50×14 mm. I had bed rest for these two weeks and in the 1st report I had bleeding but it stopped after taking med in 2 days. In those two days it was occasional. I have not experienced any bleeding since 10 days. But yesterday I experienced a drop of dark red colored blood after taking hucog 5000 injection. Should I be concerned. Thank you for responding.
