Last period date or ovulation date?

[helen9]

Just out of curiosity, for those who have had a scan already, did your baby's measurements add up to your last period date or when you think you ovulated?

My babies always measure to ovulation date. My luteal phase tends to be around 14 days but my cycle is about 45 days so when they go by my period it's out. I think it depends on your cycle though.

Mine go by ovulation date I have a 16 day luteal phase

Mine measures smaller than LMP but larger than ovulation!

My LMP was 5th December which would make me 13+2
‘Ovulation’ was 25th December which would make me 12+3
(Ovulation pinpointed by positive OPK and temp shift)

However I’m measuring 12+6!

By last period I'd be 10 weeks 3 days, by ovulation I'm 9 wks 6 days by doctors measurements I'm 9 wks 3 days so I think for me everything is off

I got dated a week ahead so my date scan definitely went with my early ovulation date.

Last period puts me at 10 weeks and bean measuring at 10 + 1

Thank you guys! I'm so confused on how they work it out, by LMP I should be 7+5 but by ovulation date I should be 5+5
