Just been told both tubes r blocked but i have 2 kids and never had an infection etc.so y would this happen plus told cant have them unblocked either?

Endometriosis?: There are several causes for blocked fallopian tubes. The most common is pelvic inflammatory disease but if you have not had infections then this is probably not the cause in your case. Other causes are prior surgeries and endometriosis. Only your gynecologist could tell you what might be the cause in your case. In cause of scarring in the fallopian tubes can cause them to be blocked.
