    Both babies measured consistently a week behind despite us being sure of our dates - and there is no debating IVF dates! Both had caught up, or were ahead, by 8 1/2 weeks. If this is a natural conception it could just be that you ovulated later than you thought, or bub took longer to implant.

    Also, if you have a tilted uterus (I do) it is not unusual to measure behind. It doesn't necessarily mean bub is small for dates - they just can't view things accurately due to the tilt. As the pregnancy progresses the uterus flips forward and voila, there is baby measuring back to date

    ETA: Remember that we are dealing with a baby that measures a few millimetres at best. It is so easy to move 1mm either way and throw dates out by a week!
    Thank you for the reply.
    This is a natural pregnancy, I must have ovulated later as I remember thinking I can’t be pregnant bc we dtd after I ovulated.
    I do have a tilted uterus, but he did an internal ultrasound so assumed it was fairly accurate.
    You are right though, 1mm here or there throws everything out.

    Just as much room for error with an internal as with an external I always had internal ones done too.

    Positive thinking for the week ahead.

    If you have a moment, would you mind explaining how the date of the first pregnancy test fits in with it all?

    Ok so if I play around with your dates this is what I come up with - which is very possible (obviously speculating as I don’t know your definite timing and dates etc)

    Positive home pregnancy test 8/11 (10 days post ovulation = dpo)

    Blood test 13/11 HCG 555 (15dpo) (4wks1day pregnant) - I’m saying this is possible as my DD was 520 HCG at 4wks1day (IVF bub)

    Scan 1/12 - scan measures 6wk1day but real dates are actually 6wks 5days. Meaning only 4 days difference which is not a big deal at all

    As others have said - bubs is tiny at this gestation so measurements could be out just due to inaccuracy in measurement

    I know anything could happen but your numbers and dates look pretty good. Think positive and I’ll look forward to hearing from you in a week

    The dates can be a lot different to what you would expect. Eg my husband wasn’t even in the country during the supposed ‘fertile time’ for both of my pregnancies and he is 100% definitely the father! There’s a lot more variability than literature states. You really just have a waiting game on your hands.

    I can’t really remember.. it wasn’t faint, I didn’t second guess if I pregnant. I should have taken a photo. Why do you ask?

    Just a thought about the darkness of pregnancy tests, mine never went super dark. Some women don’t ‘leak’ for want of a better word hcg as strongly as others.

    I did another test sometime between 11th Nov - 22nd Nov & it was dark.
    My HCG with my first bub was 44000 around 7 or 8 weeks.
    I have another scan booked for Saturday so we will find out then I guess 😳
