I don't know hon, as I haven't delivered a baby yet. But I do know my when I had my MC, it was like contractions...and I had the pushing urges.....I'm glad I'm not the only one who had it that way. I thought I was a freak, but it wasn't like anything I've ever experienced. If I wouldn't have known it was coming (no heartbeat on the US), I'd have went to the ER for sure.
My doctor (both OB and my primary care) told me that after 2 c-sections that a VBAC would be really dangerous so Im not sure what to tell you on that one. I would talk to your doctor to make sure and to find a doctor that specializes in VBAC's. Because after that many C-sections you would really need a specialized doctor. Good Luck
I had a miscarriage at 5-6 weeks and that wasn't nearly as painful as laboring a full term baby. Your body doesn't have to fully dilate to expel this sized baby. I also think it depends on you and your pain tolerance though.
