Mommies - when to try for no. 2

I have been thinking a lot about trying for a second as soon as possible. I want to get my shape back first so that I do not have a ton of extra weight. When do you all think is enough time I was going to try again around 8 months. Or is anyone already thinking about this? I just am afraid to go through another 2 years of miscarriages. My OB/GYn knows my issue from my RE and said the minute the stick turns blue to call him and he will get me what I need. I am just scared to go through 4 more losses and another 2 years. I would like to have 2 more in the next 6 years.
