Perpetually confused

*Edit: They are going by the due date of March 8, so I'll be considered 40 weeks along this Saturday. The nurse also said the swelling is probably a lymph node related to the recent colds/drainage I've had and just to keep an eye on it for further swelling, heat in the area, or fever. So there ya go--less confused now.

Yep, that's me. Today, another appt with my midwife, since Zachary is taking his sweet time coming out. I realized I have 3 different due dates on my chart, one is March 8 according to the first U/S, the next is March 16, according to my last period, and the last is March 19, according to the last U/S. *sigh* I think they're going by the first one as of now, but I did call back later and left a message with the nurse to verify that. My midwife told me if I go past 41 weeks, they will want to do another U/S to check fluid levels, and if all is ok, then they won't worry about anything until 42 weeks has passed. So, I want to be sure what week of gestation they are considering me to be in so I'll know what to expect when.

Then, I took Zoe to McD's for some playland time, and I discovered I have some swelling on my left jaw muscle right in front of my ear. It's really sore to the touch too. I have no idea what it is. Maybe clenching my jaw when I sleep? Mumps? Drainage? So, another call to the nurse's voicemail. Hopefully she'll call back soon, so I won't be so confused.
