I think I'm out...

AF due today. I've just taken a test and it's a BFN...I just want to cry. I can't silence that little voice in my head that says it may never happen again for us. I still have nausea and twinges of pain in my breasts, but must just mean evil AF is on her way. Now I just wish she'd hurry up and start so I can plan for April. Why is it we spend YEARS preventing a pregnancy and then when we want a baby, it just can't simply happen? This is baby #3 for us, you'd think our bodies would have it figured out by now. This is so frustrating...
