How do you figure out how many weeks?

Jenojeno

We have been TTC for several months and I went on Clomid to ensure the little eggies were dropping. Since I knew exactly when I was ovulating, we had plenty of sex and, here we are a few weeks later with a positive pregnancy test and doctor confirmation. Yay!I'm trying to figure out how many weeks pregnant I should "consider" myself. Calculate the weeks since my LMP? (which would put me at 5 weeks?) Or since conception likely happened, which puts me in the 3 weeks range? Seems that the "norm" is since LMP, but that just feels a bit odd.Thoughts? Thanks for your help!!!!

LMP. That's how the doctor will calculate it unless they do a dating ultrasound. There's no way to know exactly when conception happened.

Do you mean you ovulated 3 weeks ago? Then you would be 5 weeks pregnant. You always add two weeks to the conception date (since pregnancy is dated by LMP and the "average" woman ovulates 2 weeks after the beginning of AF).

Doctors go by your LMP, so that's what you should go by.

I was BBT charting and using ovulation strips. I know exactly the day I ovulated, and according to my temperature readings, I have a very good idea of what day implantation happened. When they told me I was 4 weeks along when I got my doctor's confirmation, I was like, "Yep." And when they were about to say when my due date was, I said, "November 5th." The look on the nurse's face was priceless! XD

Yeah, the doctors have all been going on the first day of my last period. But at the ultrasound it was figured that I was 1/2 a week less.
