Yesterday was the OB appointment, and unfortunately when he checked Mina, he found she was dilated to 1 cm (but not effaced any more than before). Her blood pressure was also 134/89, which is pretty high for her. So now, Mina's modified bedrest has turned into full bedrest. She can still take showers and use the bathroom, and station herself on the couch instead of the bed if she wants, but she needs to spend most of her time laying down.
We need to make it to at least 34 weeks to give Charlie his best chance possible, and Mina will be 33 weeks tomorrow. So lots of prayers that she just makes it at least one more week, if not the full 5 more weeks we had planned on! Thanks everyone :)
