Hello dear, I understand your concern. Iam sorry for your condition. In my opinion the bleeding after a positive pregnancy test might suggest miscarriage. But the definite diagnosis is possible only after physical examination and ultrasound. The bleeding during pregnancy can be due to various reasons like miscarriage,bleeding from cervix,hormonal abnormalities like thyroid abnormalities,progesterone insufficiency etc. In a few cases the pregnancy continues normally when the cause is treated. So I would like you to consult doctor and ultrasound done to know the status of pregnancy. Dont worry.Avoid stress,physical strain and intercourse.Take good rest. Hope this helps. Best regards ....Dr.Srilatha
