No. I've said it before and I will keep saying it until ASP proves me wrong: The whole entire show is based on a mistake that Lorelai made when she was 16. Just because it turned out good for her does not mean everyone should go around saying "Birth control? Who needs it?" That basic sentiment has been restated in various seasons over and over again. I just don't think there's anyway that Rory would make that same mistake. Sleep with a married man, not go to college, sure...but not that.
And, let's keep in mind. If you're saying that Rory getting pregnant is why she dropped out of Yail, that can't be true because several months have passed (both in real life and on the show).
I'm not directing this towards anyone in particular, so don't get offended. I just have a very very strong opinion about this particular subject.
