Early ultrasound wrong calculation?

Hi everyone,
I'm curious to hear from people with a similar experience... My last period started on December 19, 2018, and I got my first positive test on January 18. It was very faint at first, but turned darker after a few days. According to my calculations, I should be 8 weeks pregnant now, but yesterday we had our first early ultrasound. They couldn't see the baby clearly externally, so they did an internal scan instead. Based on the measurements, she said I should be around 6 weeks and 1 day pregnant. That's quite a big difference. So she explained that either the baby stopped growing at 6 weeks, or I had a slower implantation process. She mentioned this happens sometimes. Now I'm leaning towards the first option but to be sure, I need to come back for another ultrasound in a week. I'm wondering if anyone here has experienced the second scenario and had a similar difference in weeks, but everything turned out fine in the end. I know I just have to wait, but this uncertainty is so tough..
Xx

    Mamavanjayden I'm sorry, but I can't give you good news. I went through the same thing in October. I was supposed to be 7 weeks, but it was estimated at around 5 weeks. Was there any heartbeat? I did read some positive stories here and there, but 2 weeks is a lot to be set back. I hope things work out differently for you and that you can look forward to a healthy pregnancy

    Hi San1989,
    Oh that's so awful! Yeah, I have to say I'm also going by that. With my son, the calculation was correct and they immediately saw a beating heart.
    Now they didn't see a beating heart, she said that can also be completely normal at 6 weeks. But indeed, I find the difference of almost 2 weeks too big to be pushed back.
    Well, we'll see, just wait a bit more.
    Thanks for your kind response

    No good experience here either, but given that your test was still very light back then, could it be a difference of a few days? Or are you very sure about your ovulation? Hopefully good news for you in a week's time. Two weeks is a lot, but everything is still very early. Wishing you lots of strength for the coming days, especially while waiting until next week.

    As you already said, the only thing you can do is wait. But from me, I wish you a positive story. I was also put back 2.5 weeks during the pregnancy of my daughter. I didn’t understand it either. Later in the pregnancy, they added another week, but it still differed by about a week and a half from what I had calculated myself. She was born spontaneously at 36 weeks and 2 days and is now a healthy 3.5-year-old girl. By the way, during the first two ultrasounds, we also didn’t see any heart activity.
    I’m rooting for good news at the next ultrasound!

    Thank you! I'm not sure about my ovulation, but we'll wait and see

    You're right about that. It's nice to read a positive experience, even with such a big difference. Weird, indeed, but you never know. We'll wait and see! Thanks for your kind response

    A 2-week difference is too much. Not good news, I'm afraid.

    Strength while waiting.

    For me, it's 2.5 weeks less. Everything has been going fine so far. I think I had a late ovulation or something. So it doesn't have to turn out bad at all.

    So early in pregnancy? I don't think you can test positive then. Take it easy.

    We'll see, girls.. I have a new ultrasound next Tuesday. I hope I'll have some more clarity by then

  11. San1989 #12

    Mamavanjayden I'm rooting for you, okay? It can go either way, as you read.

    Hey,
    I'm in exactly the same boat. Even our dates are almost the same. Just check out my topic for my story. I also have my second ultrasound on Tuesday at 5:45 PM. Good luck I find the waiting really awful, and the uncertainty even worse. Hopefully, everything will be okay for both of us.

    Hey sweetie,
    Oh my, I read your story. Coincidentally, I was also supposed to have my ultrasound on the 14th, but I moved it to the 12th. We're indeed in the same boat. It's annoying, isn't it, that uncertainty
    I hope we both get good news next Tuesday.
    Strength while waiting these days

    Merci. You too, stay strong. It's really frustrating to wait, but there are also positive stories here. That gives some hope only 3 days left.

  15. San1989 #16

    Mamavanjayden any news? How was your ultrasound?

  16. MamavanJayden started this #17

    Hi girls,

    The ultrasound wasn't good. The baby was still measuring at 6 weeks and there was no heartbeat. I had already prepared myself for this, but it still hits hard

    I'm going to wait a week, because I've started bleeding a bit since tonight. It's not a lot yet, but I hope it will pass on its own. Otherwise, I'll start the pills next Wednesday.

    Thanks for your kind messages

    Do you know any more cute names? I hope you get good news

    Same here for me.. Stuck at 6 weeks.. I start taking Cytotec on Friday. Lots of strength, dear, this hurts. Hopefully we'll be pregnant again soon.

    Wishing you all lots of strength, ladies

  19. San1989 #20

    Oh no. I know exactly what you're going through. Sending you lots of strength
