Alexis, I have also been ttc for 2 years with all my tests fine, so Im unexplained. I spoke to the fertility doctor recently as we have another year to wait for ivf. I asked him if he thought we had any chance of it happening naturally now thats its been 2 years and he said absolutely yes it can happen and he sees it all the time. He also reassured me that he feels like theres nobody in our area he hasnt seen, so its far more common than you think. It may be worth speaking to somebody about how youre feeling as it must be awful to live with the way youre feeling constantly. I went through a rough patch recently but thankfully Ive come out the other end now. Ive mainly just refocused my attention on other things, like looking after myself, spending time doing hobbies, giving myself career goals for a years time etc. Thats not to say I wont have bad days and it is still on my mind every day, but for my own sanity I had to find a way to deal with the disappointment and heartache of long term ttc. I didnt want to look back at these years with regret and sadness. Life is too short for that. I really hope you feel better soon (or even better, get a bfp!)
