How Accurate Are The Doctors In Determining How Far Along You Are In Your Pregnancy When They Use The Ultrasound Machine?

Based on the ultrasound machine I'm 10 weeks but that puts the first day of my last interval on Sept 7th when it was august 30


Answer:
It's possible you ovulated late.  When it comes down to it, it's not when your last interval was that really matters, it's when you ovulated.  Doctors just use your finishing period as a reference to estimate when you're due, as most women ovulate right in the middle of their cycle.  What most women don't know, when it comes to the timing of their cycles is that it's not exactly two weeks after your length that you ovulate.  Instead, it's you get your period two weeks after you ovulate.  So it's not your period that cause you to ovulate, it's the opposite.  It's ovulation that causes your period.  So I would bet explicitly what's going on, especially if you have a history of irregular periods.
