TTC OVER ONE YEAR. NEED SUGGESTIONS

I know some people take years to conceive.. I have endometriosis and had a cyst removed back in may 2016.. Trying to get an opinion of when I should start seeking further help from a reproductive specialist. 
She has given me the option to have a shot every month x 3 months to further help treat the endometriosis but that would put me in temporary metapause and further delay our attempts to conceive right now..Suggestions?
