So in terms of the point in gestation, why does that matter so much, where they are in pregnancy?

Well, certainly different things can happen at different points in a pregnancy.

So in the first trimester, women may not be feeling great, or there's a potential risk for miscarriage.

And so whether that's gonna happen somewhere far away or during a long flight, those are kind of the things you are gonna worry about.

In the third trimester, close to your due date, you're thinking about, could you go into labor? Could your water break? Could you have a concern that you would wanna go see your doctor the same day or the next day for, and if you're far away, how are you gonna do that, and where are you gonna get your care, and things like that.

And what about in terms of, you said, what their own history is, like what their own, how the pregnancy's been going.

Right.

So for patients, let's say, who've had a history of a preterm delivery at 30 or 32 weeks, we may feel more strongly about them not traveling at that point in their current pregnancy, as opposed to someone who has never had that history, and therefore, the risk of a complication or going into labor at that point is a little bit lower.
