I had my early dating scan the other day, which was amazing! Now I know baby will come whenever he/she is ready but still curious that the sonographer told me, based on measurements, that I was actually 8 weeks not 7w4d so due 3 days earlier than calculated by my LMP. The weird thing is that I'm almost certain I ovulated on CD15 because my BBT spiked on CD16. But being 8 weeks would mean I actually ovulated on CD12 which is very early and I had no signs of ovulating then. I also had an implantation dip on 9dpo which matches my predicted ovulation date. Is it possible baby is just growing quickly and it's irrelevant when I ovulated? Could it be because conception happened so quickly after ovulation because we only DTD on CD12 and CD15.
Anyway, I asked her which we go with, ovulation date or foetus size and she said it really doesn't matter, we can just pick either date but we must stick with it. Anyone else have this happen?
