18 weeks...again

At our ultrasound that we had last Friday, (which will be my next post, of course) the baby was measuring about 8 days behind and the u/s tech said that Dr. Lemberger usually changes the due date if it's more than 7 days away from the original due date. If so, that would actually put me at 17 weeks 6 days, I'll be 18 weeks tomorrow. And since I've already done an 18 week update, obviously I'm not going to do another one. I'm assuming she will change it because, 1 - the u/s tech said she usually does, and 2 - I'm going to tell her I really want her to change it...it would give me more time to go into labor on my own! So that's that. My next dr. appt. is on June 7th. We'll see what happens.
