I had a c-section that was planned. My first child was also born by c-section (emergency).
My doc said I was perfectly fine to try to have a VBAC. I think if they cut your uterus vertically you have to have repeat c-sections, but if they cut horizontially you are perfectly safe to try to deliver naturally. I may have that a$$ backwards.
The way our hospital works is if a woman goes into labor that has had a previous c-section the OB on call has to stay close by because of the risk of complications. So a lot of doctors try to talk patients into having repeat sections so they don't have to be there for what could be days, depending on the woman and how long her labor lasts.
I had a lot of anxiety about delivering naturally and chose to have a c-section. It had nothing to do with fears of ruining my vagina, or any vanity on my part. It also had nothing to do with laziness. I was terrified to do it and my doctor told me I didn't have to. I did like the fact that I knew when my son was coming so I could prepare.
My incision was a bikini cut. It's along the top of my pubic hair in between my hips. It's about 5 inches across. I have no scars on my belly at all. Of course it's noticable if I'm naked and someone is right down there.
