The biggest factor was insurance. I won't have insurance coverage until January, so we thought we'd start trying early 2014.
My brother and his wife just had a baby, and I'd like for them to be close in age, which is not really a deciding factor, but a nice bonus.
We've had some financial changes, which have made the idea of having a baby less intimidating.
And we're going on a romantic vacation in December, and who wants to use condoms on vacation? So we thought, hey, what difference does a month make? You don't see a doctor when you're two weeks pregnant anyway.
We don't want a dead of winter baby (almost everyone in my family was born between November and January, and I don't want to go into labor in a blizzard), so we'll probably just NTNP through February, prevent for a few months, and maybe get a bit more serious from there. I'll be 31 in a few weeks, and I definitely want at least two kids, so I don't want to dilly dally for too long.
