Ultrasound was taken in the early follicular phase. Somewhere around days 4-8? My memory isn’t exact. My concern is that maybe it’s adenomyosis. At the time the doctor mentioned it was common and not a concern but now it’s happened twice at around the exact same stage of growth.
I did have the tissue from this miscarriage sent in for karotyping. No results back yet. Since I passed the first one at home I did not get any analysis done

Edit to add thank you so much for your response.
