Miscarriage question.

Brooklynn • Due April 2020 🌈 👶💗💙

I had my first miscarriage 6 years ago but at the time I was 8 weeks pregnant and in a relationship with an abusive boyfriend who I thought caused me to miscarriage. Now I am married to a great man and we had a miscarriage back in December at about 4 weeks... When I went to the hospital for bleeding they did a transvaginal ultrasound and didn't tell me anything but that there was nothing in there. If something was wrong with me like something that they could see with doing the ultrasound of my reproductive organs would they have told me? I've had tests done and there is nothing wrong with me.... So why would I have recurrent miscarriages?... It really sucks. I only want 1 child, that's all but I feel like being pregnant and staying pregnant is the hardest thing. I can get pregnant easily but I didn't try after my miscarriage until now because I have been so scared.
