Hello, I would be happy to help you with your question.
So it sounds like you likely started the pregnancy
with twins, but one of the twins has miscarried. Sometimes there is no bleeding, but sometimes there is a small amount of bright red blood or a brownish discharge as the miscarrying twin resolves. Your doctor is not totally correct - there is sometimes symptoms related to the miscarriage
of the one twin. The lack of significant pain or cramping is a good sign. There needs to be a followup ultrasound
in the near future to resolve this question completely.
I hope that this helps. Please contact me through the PREMIUM SERVICE if you would like more detail or a more timely response - Dr. Timothy Raichle
