Would i be considered infertile if i've been ttc for almost 3yrs but i don't have intercourse every other day, i have sex bout 5-6 times a month!?!

Yes, seek help: As long as you have been having intercourse without protection for more than one year you would be considered infertile. Even at 5-6 times per month over 3 years time you should have come up with a positive test. I would recommend that you see a doctor to evaluate if there is any reason you have not conceived.

Yes: 'infertility' is defined as a couple that has unprotected intercourse without conception for one year. This is based on observational studies demonstrating about 85% of normal couples conceive in that time. This definition does not depend at all on 'actively trying, ' just that a sexually active woman is at risk for becoming pregnant with her partner during that time frame.
