Im so nervous.

I have two beautiful kids a two year old boy and a little girl who is about to turn one march 18th.. i had a uterine rupture in three places due to a c section with my daughter. My hubby has been wanting another child so badly but each time i am late every month or dont have one at all we always end up disappointed.. well now i am three days late took a test on wednesday. It came back negative... Now i am sitting here thinking would i ever get to have a third child after those miscarriages or what??!?!?!
