How many weeks am I? Please help me out

I'm trying to figure out how many weeks along I am because my doctor's calculations keep differing from my own.

My LMP was Oct. 4 which would be 17w 1day today (Feb. 1).

My first Dr. appointment was 12/15 and they said I was 9w 1d based on the sono and gave my EDD as July 19.

My next appointment was 1/11 and they did a 3D sono (Level I) and that came up 13w 5d which put me at July 14.

At my last appointment on 1/26 they had 16 weeks on the paper.

Based on my originial sono in Dec, I would be 16 weeks today (Feb 1) but based on the second sono it would be 16w 5d, and the last appoint which no sono was done, that would put me at almost 17 weeks.

I can't keep track. My next appoint and Level II is the end of Feb. Maybe I'll just wait and see what they say then.

Did anyone else's dates/weeks keep changing? So confusing!

Personally, if it were me, I'd just go off my LMP until they specifically told me otherwise.

It isn't typical of OBs to constantly change your EDD because the measurements can be so flaky.
