Possibilities To Get Pregnant After The Bypass?

Life after the bypass surgery, Is it possible for someone to get pregnant after the procedure? I haven't done the procedure yet. Before I do decide to undergo the surgery. I'm hoping after the surgery is completed. How many years should I wait to have another child. I already have a five year old. I was hoping five years from now to get pregnant again. I plan on doing the bypass in the summer of 2017. Please and thank you for all the advice's.
