Advice please!

Judy • Thank you God!
Hi ladies,
I had a miscarriage last month (12/15/14).  I already had my regular period this month.  I want to try again.  (Me and my husband are so ready to have a baby). My doctor told me that I can start trying now but honestly I am very scared to have another miscarriage.  I would like your advise from any previous personal experiences!! Please respond, I really appreciate your help!
