OMG, this is almost exactly what happened to me!
I had surgery at 34 weeks pregnant - they wouldn't give me a GA or any type of sedation so I had to lie there wide awake whilst they worked. I took my iPod so that I couldn't hear it all and tried to ignore it as much as possible. Were you the same?
Originally, they told me 6 weeks non weight bearing, but it only turned out to be 3 in the end. Or rather 3 after surgery, it was 9 days after the accident before I got my surgery.
I was supposed to still be in plaster at the time of the surgery, but the very sympathetic female ortho consultant put me in a removable boot to make things easier at the time of the birth. I got myself a Limbo cast cover which was extremely useful, indispensable in fact!
I was to be consultant led anyway because I had previous CS and a bicornuate uterus. His plan was continuous monitoring, coming to hospital early, possibly going to a EMCS sooner than otherwise etc etc etc. When he said that, I thought Fuck That and wrote my birth plan saying that I wanted as few interventions as possible, birthing pool, immediate skin to skin and so on. The midwives followed my plan pretty much, although I did have to have DS2 lifted out with forceps, but it was not an aggressive forceps delivery like you sometimes read about.
My Limbo cover fitted over the removable boot, so I was able to wear it in the birthing pool. It was a bit weird because it made my leg float, so I lay on my front in the water, but that wasn't really here nor there.
One thing I really disliked was that ortho and obstetrics agreed that I should inject myself with blood thinners to reduce the DVT risk. I am not squeamish, but I really didn't enjoy injecting myself every day. I would be a rubbish druggie 
At first, they were not going to give me crutches, but I persuaded them to at least let me try them. I found them easy, but apparently not everyone does. The physio taught me how to hop up and down the stairs, but I limited myself to only doing this once a day as it was really hard work! We only have an upstairs bathroom, so my midwife organised a commode. A bit grim, but hey, I had to pee somewhere!
DS1 was not very impressed, he was 4y 4months at the time and was being sent here there and everywhere to be looked after. I could deal with him much better once I was weight bearing, but the upset at the time and then adding insult to injury by bringing home a new baby really took it's toll on him, wee soul.
I am looking back at it now 4+ years on, but I have not forgotten how bloody hard it was at the time. You will get through this, but it might be a bit crap getting there.
