subsequent pregnancy gestation length search

Jan 20, 2013 10:28

Hello group! So let's see... been a while since I checked in but I am now at 24 weeks and just like last time, I'm now bored with counting weeks and have started writing scripts. My big due date survey is still running, actually it's really caught on, I have almost 3500 responses which is enough to really dig into some weird numbers.

So I made this, for all you non-first time moms:
Subsequent pregnancy due date search

You can type in when you went into labor last time and it shows you others in the database like you. For instance if you were four days early, it will show you all the other moms who had their first baby four days early (plus or minus a day, you can set the range to whatever you want), and you'll see that on average their second baby was only two days early. If you were eight days late, it can bring up the 10 women who were also exactly eight days late, and it turns out on average they were only four days late on their second... oddly enough that's how most of the dates seem to be working, everyone sort of drifts towards the middle. And anything can happen, no matter what date you put in you'll find a range of possibilities that women have reported. Due dates are all sort of a crapshoot still (only 30% of women who hit their due date the first time managed to do it again). But it's fun to look at statistics, if you're into statistics.

It throws out all inductions to form the averages so all the data is based on people who just randomly went into labor without knowing the day or the hour. And I do have a page analyzing what inductions in general do to the numbers (ie, if we didn't induce labor, what would these averages look like?) because I know that's an important topic these days.

Anyway, my due date is May 8 but I was really hoping for four days early to have the baby on Star Wars day, looks like on average since I was two days early last time, I'll be two days early this time. I guess we'll see!
