BFN - Again

So, I tested for like the fifth time this week, and the test was negative. I am supposed to see AF tomorrow, but I usually start spotting the day before. That isn't happening. I am still holding out some hope that I am pregnant, even though the test doesn't say yes. My temps are in line with other cycles, but my coverline is much lower this cycle. I hope that's significant. I really wanted to get pregnant in 2009...
