I had a miscarriage 2months ago and now trying to fall pregnant but scared that I will have another miscarriage, what can I do to prevent a miscarriage?

Nervous. . I understand you may be anxious. Miscarriage is relatively common and most likely there is nothing you can do to prevent it. Try again. If you have three miscarriages in a row, seek evaluation for a work up. Some physicians will start a work up after two.
