Just got back from the doctor. I'm fingertip dilated, which explains why I've been losing so much mucus (passed another big glob this morning). Although last week's fFN test was negative, TheGoodDoc thinks it's possible I may go into labor as early as this weekend. She's pretty certain I won't make it to my Feb. 5 scheduled section. She brought in the partner who's on call this weekend to introduce us and go over my case, and told her if I'm dilated to 2 or 3 centimeters to go ahead and do the section. I have instructions to call if the contractions get to 7-8 minutes apart for 2 hours.
However, we did also make an appointment for an office visit next Tuesday, in the hopes that if I take it really easy this week, I can make it at least until then. Fingers crossed.
