New Due Date?

So I went to my appointment on Monday and while there the PA measured me and I am still 2 weeks ahead, so I asked if I could get an ultra sound (I'll scan those pictures ASAP) to check the due date and I am measuring 11 days early according to the ultra-sound. Potentially then my due date could be September 19th and I could be having a baby by early September if they induce me early so I can try for a VBAC. All these ifs are making my head spin. Oh well, hopefully our next appointment with the doctor in 2 weeks we will find out more delivery details. Stay tuned...
