Almost 2 years and getting discouraged

So over a few weeks and after a multitude of tests we decided to try a combination of provera, to force my period, and chlomid to force ovulation. I was over the moon. I had heard so many success stories for chlomid that I thought "surely this would be our time." Well, the first round of chlomid I had such high hopes, even after not getting any positive opks at home. I thought "surely I'm just testing at the wrong times and I missed my window. No problem we BD every other day from AF end to AF stats just to be safe."

I go in on day 21 for the progesterone level test. I was positive I'd get that phone call telling me "hey! It's ok, you ovulated, just keep trying." Instead I was told the chlomid had failed. We did not ovulate. I was crushed, but I told myself it'd be ok. That next time it would be our turn. Round two of chlomid. I convinced myself again that I was just missing the opk test window. Even testing multiple times a day. But no, I didn't miss my window. The chlomid failed again. I want to request a stronger dosage for round three, but if two rounds failed then what is the chance that a third will succeed? Everything is just taking its toll on us. I cry most days now. I cried unreasonably and woke husband up last night because he was exhausted after a very trying day at work and having to work over and he fell asleep before I even made it upstairs. 

I was upset because he fell asleep, we hadn't  BD in two days, and I really just needed some comfort because I had a rough day as well. I felt hurt that he'd rather sleep than spend time with me. That was not the case as I can rationally admit but I was anything but rational at the time. My wonderful, sweet, caring husband understood. He woke up, he held me, he comforted me, and once I was calm and content again he initiated BD, and made me even happier.
