Baby news-scary times-way behind

So I am in my third trimester (almost 29 weeks to be exact) and it definitely feels like we are in the home stretch. My body aches all the time; I'm just very thankful that I had a very easy 6 and a half months before this so I figure 3 months of pain isn't too bad! She is moving around a lot-she still hasn't move up any...most of the preggers people I know told me I would feel her around my rib cage and things but she is definitely settled towards the bottom-which means lots of kicking on my bladder! Whoopee for me!

But we did have a little scare yesterday...I woke up and noticed some spotting. I was told that if I noticed anything like this to call the doctor immediately, so I called today (they aren't open on Sundays obviously) and made an appointment. The appointment was moved about 3 times and I had to see the nurse practitioner because my doctor was out delivery another baby. They are running several tests to see why I had spotting and some cramping today. They tested for infections and also for fetal fibronectin.
FF is some sort of hormone/chemical that indicates if you might go into labor early. If the test is negative for that then I don't really have to worry about anything, but I will be tested and looked at more often. If it tests positive that means I'm highly likely to go into preterm labor-there are things they can do to prevent a premature birth or to help her lungs grow faster so that if she were born early she would be okay....but that is something we'll worry about if the test is positive. I'm trying to remain optimistic and not worry so much about it, but if you know me then you know that I stress out about everything.
I'll keep you updated on that.

The other thing I wanted to mention is that I am WAY beyond behind in grading and school related work. I'm glad that this is the last week before Thanksgiving and I don't plan on handing out homework really, so hopefully I can get caught up. So little time and so so much to do!
