After a miscarriage what should I do to try for a healthy pregnancy next time? How long should I wait after a d and c?

Pregnancy. After a d+c wait for your first normal period before trying. Eat healthy, exercise, and take daily vitamins. Eliminate any drugs or alcohol if you partake. Ask friends and family and I am sure you will find multiple people in that group who have miscarried and gone on to have successful pregnancies. This should reduce your anxiety.
