Juat Had A Miscarriage. What Should I Do?

Hi all, today is supposed to be my 9th week. I went to the gynae for a scan and found out that the heartbeat of my baby had stopped. My husband and I were devastated. Until now, we cannot believe it happened. The gyane suggested that i can go for an operation to remove my baby, or i can allow my body to let my baby out naturally which might take up to 2 months. He also suggested a third way, which is through medication but he said it might not be very effective. May i know which way should i follow? Is there any food or anything that i can do to prepare for next pregnancy? I am at a loss.
