I had a c-section on Jan.7th how long should I wait to get pregnant again?

On January 7 I had my 3rd c-section and had a beautiful full term baby girl, Savannah, 11 days later she died due to multiple congenital birth anomalies. I know it hasn't been very long at all, but I know I want another baby. The only thing is I'm not sure when to try again, my husband is scared to try again for fear of losing me. The doctor said with the c-section that I lost a lot of blood due to scar tissue from the 2 previous surgeries, with that he had reccomended against any more children. We know we want one more regardless. How long should we wait?
