Yes, you have chances. I had a uterine rupture in 2002. I had a miscarriage in 2006 and I am actively trying again. I belong to a support group for women who have ruptured have gone on to have successful pregnancies. It really depends on the severity of your rupture etc. Ask your doctor.
You need to go into the expert forum for gyn and ask a doctor...look to the right of this post for it.....good luck
