Further to a t/v ultrasound, fetal pole measuring 6w6d, no heart beat. Dr said expect a miscarriage. 6 days since u/s, no bleeding. What next?

3 options. I am sorry you have to go through this difficult experience. It may be several days to weeks before you pass the pregnancy spontaneously. You can wait a while longer, or take medications to make your uterus contract to induce the miscarriage or have a surgical procedure (d&c)to remove the pregnancy. Your doctor should discuss all of these options with you.
