I did study my calendar and found to some relief I couldn't have had a regular period becuase day 14 of ovulation would have been in the middle of a week my husband was gone and if an egg can only live for 24-48 hours this can't be possible. Is it possible that I conceived on the week he returned home - ovulated late... but it didn't implant until the last day he was home...makeing me 6 weeks as the sonogram shows...??

Lol. Have you had your first sono yet? My guess is you will actually measure a little behind compared to your LMP if you O late. It's kind of interesting but I drove myself nuts trying to understand!!
Yes I had one. I know the exact day I ovulated because I was charting, and my measurements correspond perfectly to that. But yeah I would be measuring behind if they used lmp.
So Madison, I ovulated 8 weeks ago, but I am considered 10 weeks pregnant.
Thank you Monalissa! Please help me understand further...so you said if the sonogram was taken 6 weeks after ovulation it would show... 8 weeks? I'm confused
Yes, that's what I mean. The two weeks are included, the same as when you go by your LMP. For example, I O'd about 6.5 weeks and my sono gave two measurements of 8.5 weeks and 9 weeks. I was measuring a little ahead even though I have a good idea of when I O'd because I know when I got my surge. I hope that makes sense...
It does make a little more sense. I'm confused...what do you mean my surge????
Oh, sorry! When we were trying I would test my urine for my LH surge which happens about 24-36 hours before you ovulate. I have a pretty good idea of when I ovulated.
To be even more specific, if you measured 6 weeks, that means you actually conceived 4 weeks ago. Just like with mine, I conceived about 7 weeks prior to my sonogram but was measuring at 9 weeks.
Try to stay hopeful, this is not an exact science. It freaked me out that I was measuring 9 weeks when I should have been 8+1 per my LMP. Please keep us posted!!
If I conceived 4 weeks ago then for me its not possible I took a test on 3/4 and i would have had to conceived on 3/7
The two weeks is the time before you even O, from the first day of your LMP. Based on a "typical" cycle (which is BS because most women don't have a 28 cycle!) you O on day 14 of a 28 cycle. Your due date is counted from the first day of your LMP even though you are obviously not pregnant then. What I'm saying is that sono dating includes those two weeks also - at least per my doc and the reading I've done. Hope that helps!!
Oh ok..I see now. But in my case...that would mean that I ovulate/conceived (i'm confused lol) at day 38 or 39 in order to be 6 weeks per sono (which was 4 weeks ago)....it it even possible to ovulate that late????
They used the measurments i'm sure. She did ask if my last period was a real one...to be honest I don't remember but i'm so regular (they last about 5 days) that I probably would have noticed. For instance I've never in my life spotted or had any period starting and stopping ect.
