Regretting tubal ligation?

Nikki
My third son was born (via my 3rd c-section) in April. Hubby and I decided not to risk having to have a fourth section so I had my tubes tied. My biggest fear was always that I'd do it and then regret it. I'm not yet to the point of wishing I hadn't had it done, but it does make me a little sad. Anyone else dealt with something similar?
