Thank you for the well wishes, ladies. I'm not a regular on this board, but I know I can always come here and find people who understand my worrying.
I went to the OB today and I'm 1 cm dilated, but my cervix is still what my MW would consider long. She sent me to L&D for monitoring and while I was spiking some pretty serious contractions, the FFN came back negative (yay!!) so they deemed them "nuisance contractions" and told me I could take magnesium if they became distractingly uncomfortable.
I have another prenatal (27 weeks) on Monday and we're going to talk more then about what to do to monitor me from here since 1 cm can mean nothing, or it can mean trouble.
I'm so glad I called and asked for an appt. Thanks. :-)
