Heve, if you know you O'd on June 1st then don't use your LMP, since unless you have a perfect 28 day cycle (with a perfect 14-day luteal phase as well) because then the LMP method doesn't work. Gestation is 38 weeks from ovulation/conception (or 40 weeks from LMP if above is true). So that means you are due
6/1 + 38 weeks = Feb 21st due date (Feb 22nd would make your last week 8 days, if that makes sense -- but Feb 21st midnight represents 38 completed weeks.)
Like I O'd on May 25th and have a due date of Feb 14th according to FF and that calculation I just did on my calendar... that's 38 full weeks from 5.25
HTH!
Oh, and Heve, I am still freaked out by being here. I'm not a "count your chickens before they've hatched" person and so feel kind of weird, but it is really really helpful to have others going through the same things, same symptoms, etc etc.!

Shannon, I completely agree with you. It is so hard not to freak - all you read on the internet is how low progesterone is associated with bad pregnancies

and you need to supplement. Then I read some articles that there's nothing you can do - supplements or no - to stave off a miscarriage. As in, there is some doubt as to the efficacy of progesterone supplements. And still other articles say hogwash to all of it - that progesterone levels vary widely and just part of natural human differences.
BUT... my progesterone at 5 weeks was a friggin 11.6! Argh. I would clearly be a lot happier if my progesterone were above 20 right now.

Good luck with your sonogram! Post a photo of your dt (dear tadpole!)

I hope to get a sono of my little one by next week too. Let's have some nice strong
