Hello, I would be happy to help you with your question.
It sounds like you were pregnant with a very early miscarriage
based on the followup tests that were negative. The "sac" in the uterus
could be related to the miscarriage and just tissue that has yet to pass. Assuming the sac that they saw was very small, I would wait to see if you pass it on your own. In your case, a followup ultrasound
in 1-2 weeks would be appropriate, and if the "sac" is still there, a D&C might be indicated.
