I can't offer you much help, but I wanted to know that I am in the same situation. I just found out that I'm pregnant, and I'm already worried about what kind of birth to plan for. I had 2Cs before, and I was also told at the second that my incision line was quite thin and may have ruptured. I think that scared me enough to plan Cs for any future children, but I also thought we were done at the time! Now I'm not so sure. I was told that there really is no limit on the number of Cs you can have, but that they should be at least 18 mos apart. I'll be watching, hoping you get some more replies.
