Hi there-
Congrats on your impending arrival. I had a c-section and tubal after my last pregnancy. After having a c-section with the first and terrible pregnancies I was dead set on a tubal. First, you need to make sure that you aren't delivering at a Catholic hospital as they won't do it. I will say, though, that the recovery was pretty much the same as a c-section. There was a little more pain in a different area where the tubal took place but it didn't last very long. Hormones? No more than normal. It was very easy and wasn't really a factor in the whole ordeal.
Hope this helps. Good luck and feel free to contact me if you have any further questions.
