Yeah having one tube doesn't technically reduce your fertility, it just means it can take a little longer than it might have cos only every second month (on average) counts. But in about 30% of cases an egg from the left will go into the right tube anyway!!
It actually gave me more hope cos on months that I didn't get pregnant I just thought "oh must have been wrong side" instead of "wtf is wrong with me!!"

Don't give up hope xx
