The trip is on.
The cervix check didn't go quite as well as I was hoping today -- it was around 2.8 cm. But this one was taken at a third location, with different equipment yet again, and this sonographer used a different measuring "technique" than the other two did. (This is the part where I spare you a description of my girlie bits.) Anyway, after I left that office, I was more frustrated with the fact that I felt like I was comparing apple measurements to orange measurements than the actual number itself.
Turns out it didn't really matter. I went over to the OB's office and explained the whole situation to the doctor there (the one filling in today while my OB is on maternity leave). She called my OB to consult, who is just sitting around waiting to experience the miracle of birth, and they both felt entirely confident in approving our travels -- even given today's 2.8 cm. There are fluctuations in cervical length naturally, and I am still far from any danger zone. Their main concern is that I need to have access to adequate medical care while I am away. DH and I have researched L&D and NICU hospitals near our parents and have the information on hand should we need it. But neither doctor had any belief that the act of flying itself would put me or the babies in jeopardy, and that's really what DH and I wanted to be sure of before we packed our bags. If something bad is going to happen no matter where I am, obviously there's nothing I can do about that -- I just want to make sure I'm not doing anything to increase the inherent risk that comes with carrying twins. And both doctors agree that I'm not.
DH and I did a lot of talking and research over the weekend, and combined with what the two doctors said today, we do feel comfortable making the journey. I am armed with the usual tips for pregnant traveling: don't carry bags, stay hydrated, don't cross my legs, walk around every 60-90 minutes, etc. etc.
I really appreciate your input and support during this little ordeal and always. I wish you all a very Merry Christmas and a Happy New Year, with good things on the way in 2010.
