Trying for 8 months

Summer

My husband and I have been trying for a baby for 8 months now.. I really thought it was going to happen this months and then of course on Mother’s Day of all days AF comes. How long should we keep trying “the normal way” until we start to try other options to help me get pregnant?

Also a side note I have endo which could be effecting my fertility but we haven’t done any tests or anything of that nature.
