Can I Get Pregnant With Severely Ruptured Uterus?

Hi, on the 7th July 2008, during labour, my womb severley ruptured, resulting in the still birth of my second son. My first son was 10lb 9oz and my son who was still born weighed 10lb 10oz. The surgeon amazingly managed to save my womb. They said I may possibly be able to one more child. I obviously grow my babies big, with being over 10lb. I am now wanting to try again for another baby. Are there any risks to me? What are the chances of me conceiving with my womb being repaired from a severe rupture (it ripped top to bottom and left to right, so i have a large cross shape of scar tissue). I hope you can offer some guidance.
