Is there a way to get pregnant if my tubes are tide? I want another baby but can't afford the reversal or fertilizations.

Bypass tubes. The cost may still be an issue but tube reversal is not always successful. A fertility center can harvest some of your eggs and fertilize them with dads sperm. The resulting combo can be placed in your womb at the appropriate time after your body has been prepared to receive the embryos.
Not unless.... I'm sorry, unless your tubal liagtion failed (roughly 1 in 100 do) your chance of natural conception is zero. Costs aside, you may have a good chance with ivf or anastomosis ('tubal reversal.') a reproductive endocrinologist can help you learn more about these options.
