I wouldn't want that many kids if I had to have a c section each time. I've had two, an EMCS followed by an ELCS, and I really don't fancy another one. Or a VBAC. That'll be us stopping at 2 then. :-)
I don't recall being warned about clotting particularly, though it's clearly a risk as you get clexane injections afterwards. Scary that you could wake up after what you think is from giving birth only to be told you've lost your legs. That's got to have a massive psychological impact.
