Changing Up Weeks...

Ok, so when I originally went to the dr for my first appointment in October, he said I was 6w5d but measured 6w1d.  I told him how I O'ed late and he said that explained it.  Well now when I go to the dr everything is off by 4 days.  In the grand picture 4 days doesn't mean anything, I just don't like being off on all my stuff from what the DR says and has on file. So...I'm going to be jumping a few days and catching up with my dr so we are on the same schedule :)  I'm crazy, but oh well!!
