Agreed the best way to go is from LMP. The first 2 weeks of pregancy you arnt even pregnant but it counts as part of your cycle. It's weird but that's how it works. Id go off of what it says for now and if you are then when u go in for ur appt the doc will give u a more accurate reading. I kno when I conceived but they still went off of my LMP which put my due date on Aug 13th after my first appt and ultrasound they put my due date at Aug 12th. I had her on the 18th. The 2 weeks before and 2 weeks after of when they consider u safe/full term to have the baby is due to the fact they don't kno conception and that babies like to come when they r rdy weather it's 40 weeks or not.

@rylansnjaxonsmommy1517 conception date is just a guess, nothing can make it the correct date, the most accurate thing is to go by LMP. That's what doctors do.

@juliaschade41, I did and it said December 9th it just confuses me bc 40 weeks from the 9th would be September 15th but according to Lmp its August 30th

You can look that up online too, along with the due date.
