Having a healthy baby after miscarriage

​I was heartbroken when I went for early ultrasound and the baby had no heartbeat and measured small. They said I had to either do d&c or take pills I did the pills no easy choice. 

​Is there risk for future pregnancies? I have one health baby from previous relationship and I worry my husband and I won't be able to conceive a child together 

​We haven't tried again since the miscarring
