    Default Raidly Rising HCG & dates behind?

    Hi Just looking for experiences (good and bad) of anyone who has had HCG levels rise too rapidly / being 2 weeks behind in dates and what the outcome was?

    Backstory -
    - LMP was Feb 8.
    - O was supposed to be Feb 24.
    - DTD Feb 28
    - AF was supposed to arrive Mar 9, but didnt.
    - POAS Mar 9, 10 & 11, all BFN
    - DTD Mar 12
    - Had blood test Mar 13, was BFN
    - AF still hadn't arrived by Mar 26 so POAS and got very strong BFP
    - Blood test Mar 27, result 5-6 weeks pregnant (they didn't tell me the numbers!)
    - US today (Apr 2) which showed approx 5 week pregnancy, sac only.
    - Blood test today. OB called and left a message saying HCG had increased 'faster than what she would have liked' and to have another blood test on Tuesday.... But again didn't tell me actual numbers..grrr!

    So now of course her office is closed so I can't ask any more questions. I can't get in for another US with her until 16th April :/

    She is concerned as I should have been 7+ weeks based on LMP (adjusted for 32 day cycle), but was only showing 5 week pregnancy, coupled with rapidly rising HCG.

    But I think I O'd 2 weeks late (esp given the neg blood test on Mar 13), and that 5 weeks is correct.

    Still concerned about the HCG rising too fast though :what:

    So.... Anyone had a similar experience?

    ETA - just adding - no bleeding, no nausea & no cramping either.

    To me it seems ovulation was march 13/14
    Which would make you 4w4d /5d
    Today. Which is perfect by the results of the u/s
    Congrats.

    Yeah, that's what I think too. But worried about the HCG rising too fast though. Just wish I had the numbers so I knew HOW fast!

    Can quickly rising hcg cause problems? Could it be twins perhaps

    Apparently it be a sign of molar pregnancy or blighted ovum...? But I've found soooo much conflicting info on that! It didn't look like twins on the scan today :/ well, it was only one sac, but I suppose that could develop into identical twins?

    Firstly, hcg levels vary so much they can't be used to indicate gestation

    Secondly, a molar pregnancy can cause rapidly increasing hcg BUT they are so rare it is a strange first assumption.

    I would say you ovulated late, are 4-5 weeks pregnant and are one of those women who just makes lots of hcg. Multiples is another possibility but honestly I wouldn't worry (easier said than done!).

    Good luck!

    Thanks @rainbow road. Yeah I found it really annoying that my GP only told me the first blood test results indicated 5-6 weeks gestation, and didn't actually tell me a number. I've looked at some of the range charts and the numbers can be soooooo different! Hopefully I just make a lot of HCG...my hormones have always been whacky, why not this too!

    Agree with others. I know it's hard but I would try not to worry. HcG is can be so wildly variant in women. Mine was off the charts early on, well beyond the top end of normal. I was expecting multiples but had just one healthy singleton.

    Hi @littlelove,

    I had a kind of similar experience but I'd only had one period in three years so not much idea of when my period was due!!

    They went by my LMP and took blood tests, and said I was 4-5 weeks. I went for an ultrasound 12 days later and they could only see a sac measuring 5 weeks 3 days. I was upset at first, but then I looked at my diary and realised it was JUST possible - if I was 4 weeks exactly when I did the blood test and got my BFP really early like 3 weeks 3 days!


    It was a long three week wait til my 8 week ultrasound where we got to see our perfect little baby. I’m now 24 weeks and he’s perfect, healthy and has strong little kicks. I am smitten beyond words!!!

    So like you, my HCG was higher than normal and that’s why I got my BFP early. If she thought that your HCG was high enough to suspect an ectopic or molar pregnancy I’m pretty sure she would have made you go to emergency dep’t right away. Sorry you have to wait - can you go to a different place?? x

    Thanks @Fi Poledancer & congrats! My OB didn't sound too concerned, just said it had risen faster than it 'should' have. She's pretty laid back, but you're right, if it was something to be really concerned over then I guess she would have told me to go to the ED.

    As it's Easter long weekend most places will be closed. But I do so have a dating scan referral from when I first saw my GP, so I might go to a local place late next week just to see if there has been any change.

    Still going to be a hard wait though!
