Like the other ladies said you would either have to have a reversal done or do IVF. You need to speak to your OB and find out which option is best for you.
You don't have to do reverse you can do ivf
hi, welcome to the forum. hang around, you'll learn a lot. i also have 3 sons, am pregnant again with what i suspect to be another boy and will probably have my tubes tied after this pregnancy if baby survives the threatened miscarriage. While your tubes are tied there is a very very slim chance of you becoming pregnant, they'd have had to grow back themselves and it's so rare that this happens. They can reverse the operation, but it doesn't work in 100% of cases and is i understand expensive. I wish you the best of luck
