Hello, I would be happy to help.
I am so sorry about your loss. So from what you are saying, it sounds like you miscarried the pregnancy
on your own (i.e. you did not require a D&C).
Given that you are still bleeding, regardless of how this resolved, you need an ultrasound
to make sure you have passed all of the pregnancy.
The next step is to sit down with your doctor and discuss these events, review any risks besides age that you have for recurrent miscarriage
should be done a full 6 months after pregnancy resolved, and CT scan
depends upon the indication.
I hope this helps - I am working here with limited information! - DR TIM
