So lost and confused??

So the story is i just had my 3rd baby she is 6 weeks old, but the big part of all this is i had csections with all three and with my third i had alot of complications to where i lost alot of blood and had to have a blood transfusion and my obgyn told me that with the scar tissue and with what happened she said she highly recommends i dont have anymore cause its to risky, which now hubby has scheduled a vasectomy because of it he doesnt want me to have anymore cause hes afraid i could die and leave him with 4 kids that have no mother but i keep getting depressed because i really want another baby so badly i have always wanted 4 kids so im torn and i know what i should do but the little voice in my head tells me one more will be ok. What's your guyses opinion should i listen to my obgyn or go with my gut??
