Please help, pregnant and confused?

my husbund and i recently found out we are pregnant with our second child. 11 weeks. the thing is our first child is not even 5 months old. our doctor advised us after our severly complicated pregnancy and delivery with our first baby that we should have the pregnancy terminated due to high risk of uterine wall ruputre. this would easily kill the unborn child and possibly myself. we are so confused and unsure of what to do. this pregnancy is obviously a ''surprise''. but im told by 2 physicians that i cannot risk this chance. also there was a long process of my uterus healing after my emergency cesarian section with my son and that factors in another risk of being pregnant so soon. please, some advice!! p.s. we were taking all precautions on not getting pregnant again so soon. but nothing is 100%. im very emotional right now, so no jerk answers please. just stand in my shoes for one moment.
