So yeah. Five Early Sign Pregnancy Tests Later (don't worry. I actually used the dollar store equivalent. Which are great except you have to first pee in a cup. Which is weird) and five negatives. Plus I got my period. I won't lie. I cried. At the movies. To see a kid movie (it was Rango. Excellent movie, by the way). It was an awkward moment for Brian. But he's awesome and held me while I cried in the dark theater with kids surrounding me.
On the plus side, I've got some good data. It appears that my cycle is actually pretty regular (who knew?) and for the last two months, my cycle length has been the same and my ovulations have been within a day of each other. So it should make timing this month a lot easier. Starting tomorrow, I hit my five day fertile period, so wish me luck!
