Questions about getting pregnant 12yrs after having tubes ti

I'm 38 and have 3 children. 12 yrs ago I had my tubes tied and burned. Recently I have met a man and we have started a very serious relationship. He has no children and since now has never thought about having children until he met me. What is the percentage of me getting pregnant? Do I have to worry about health issues the older I get? And I feel the window is so small with the time frame, if by miracle I did get pregnant. If we do continue this relationship, would he regret not having children of his own?

I will answer the questions about your pregnancy risk, but I can't speak to how your man feels--that is up to you to discuss with him!! As for the possibility of pregnancy, it is very low (like 5% or less) but the possibility is still there. You would be best off wearing a condom. Do you already?
