not pregnant yet

I've been trying to conceive for 3 years I'm late for my period this month but pregnancy test is still negative my obgyn isn't really telling me enough and this is the third dr I go to I'm starting to feel hopeless everybody keeps telling me to stop trying to stop everything I did for a year just to take a break and enjoy my marriage but I'm getting pretty sick of family and friends telling what to do left and right all of them have kids none of them ever had to try they had gotten pregnant right away am I being the hard on them?
