CD34 & still bfn

I'm getting so frustrated. Today I feel officially depressed. I'm on Cd34 and no af symptoms, no pregnancy symptoms, and a BFN this morning. My cycles have been pretty irregular lately... But two cycles ago I got af on cd34 but I was having symptoms so I knew it was coming. I had weird breast twinges most of the day yesterday which felt very similar to first pregnancy but they are gone today. I feel completely in limbo. At this point I would welcome af so I could just move on and try next month. Sorry... Just needed to vent. Any words of encouragement would really be appreciated. I feel like just hiding under the covers all day. Before, I never in a million years would have believed ttc was this emotionally draining.
