I went to see my doctor. I am now 50% effaced, but closed. So she thinks they were contractions, but that it is just my body starting to prepare. Being twins and a first time mom, I could go next week or in four weeks. We finally picked a concrete date to induce - March 7 (bummer! later than initially planned), but at least I have an end in sight. She did say that it is "very likely" I will not make it to March 7th. I would love to make it to February 25 (36.5 weeks)... that would be ideal for me at least.
I'm to weekly appointments now, so I'll keep you updated.
