The fact that your OB quoted that to you without any context is even more disturbing. It implies that a caesarean is without risk, or comes with minimal risk - this is something alot of people believe as they become more prevalent. It is absolutely not the case. Every caesarean a woman has increases her risk of serious complications and it's pretty irresponsible to imply that the risk is negligible. It's not.

Most practitioners will support 3-4 caesars. With good reason.
having one vaginally and 3 cs i can agree fully that eys there si risks and one should wonder why a dr did not fully inform of the risks the more one would have. Next year i will be having my 4th cs i wish drs did inform patients more of when enough is enough no one has told me and maybe they should have i will not know now will i. Every woman's body is different but i dont think 1 dr has ever told me of the risks of multiple c sections and they should off.
