***I would also like to add, you may consider having it done at least a year after having your last baby, not when you have a c-s. I have since learned That there is less of a risk of such problems if you wait at least a year after having a baby. But, again, talk to your doc, get a second opinion from another doc, too.****
I agree with Veronica, I recommend against it. I, too, had difficult pregnancies and decided to have a tubal with my planned c-s. I used to have VERY regular periods, they were like clockwork, every 4 weeks on the dot. Now they are anywhere from every 3-6 weeks, more often every 3 week than every 6 weeks. They used to be VERY light, all I needed was panty liners. For the first few years after having the tubal, I felt like I couldn't even leave my house the first few days of my period because it was SOO SOO heavy. I wore heavy duty pads and still leaked every time I stood up. It has been almost 7 years now and they are lighter, but still much heavier than before. My periods are longer - they used to be 3-4 days, now I get what is almost like a second period. I get a heavy one for 3-4 days, then I think I am almost done, and it starts again for another 2-3 days. I now get HORRIBLE migranes, which I NEVER had before. They start a few days before I get my period and usually last for a few days into my period. I could go on, but won't, you get my point. I NEVER knew any of these side effects. Of course my doc did tell me there were possible side effects, but I really didn't think anyone really had problems after a tubal. I have come across MANY MANY MANY people with the same problems. It is SO NOT worth it. I did go on the mini pill for awhile, trying to solve some of these problems. It did help, a little, but started a whole new set of problems. My dh and I wish they could have just taken my uterus when they did it, but, like your doc said, they only do it if it is medically necessary at the time. Do more research, talk to your doc about your concerns, check into your hubby having a vasectomy. Only you can make the decision, just make sure you are fully informed. Good luck and congrats on a new little miracle.
