Since the doctor's office is using December 22 as my due date, I went ahead and changed my ticker to reflect that. Unfortunately, those two days difference popped me back to 13 weeks. And apparently 13 weeks is still the first trimester...it's a small thing, tiny, but it still bugs me! But I think tomorrow the week shifts to 14 so I won't be so annoyed for long.
I thought someone might notice my ticker moving backwards so it made sense to post about it.
