Starting to lose hope

My husband have been ttc for 2 years and we haven't gotten anywhere.  I started to go to my obgyn to look into my options and have gotten the necessary testing for myself, however, the next step is my husband.  He keeps telling me he will get tested but every month af comes and he tells me to just wait another month and he will go.  I cancel my dr appointments bc what's the point in going when we can't move on to the next step bc my husband won't do his part.
I feel like everyone around me is getting pregnant without even trying and as much as I am happy for them I can't even be around anyone anymore.  
I have been tracking my ovulation, using fertility tea, preseed, prenatal vitamins, mucinex, etc.  
I am due for af in 3 days but I feel af coming and every month is gets harder and harder.  I just don't know what to do anymore.
