Yep, I get the lightning crotch occasionally as well, along with the feeling that everything is about to come tumbling out. Oh, the joys of pregnancy.
Zephyr, I have to say, I was kind of hoping to pop in here today and see that you'd had a sweep and were in labor! But seeing as baby is still posterior, I understand why you put it off. I hope that baby turns for you soon! When is your next appointment with your midwife?
Jess, if you want to post a picture, you go to the screen where you're typing out your reply, and if you scroll down, you'll see a button that says "Manage Attachments", and from there you can upload pictures.

But that's exactly how it looks to me, kind of thick, gooey, and yellowish, just like you have a cold and blew your nose. On the flip side, my normal discharge is usually creamier and clear/white.
