When are you safe from Vanishing Twin occuring?

  1. Hi ladies,
    I am 8w2d pregnant with twins and have yet told my side of the family that we are expecting and that it's twins. My apprehension of telling is that I have heard about the possibilty of vanishing twin syndrome (VTS) occurring happens with ~20% of women pregnant with multiples.

    Does anyone know how far into the pregnancy you are less at risk of having a vanishing twin incident occur? I have heard that once you get past 10 weeks the chance of VTS occurring is relatively low (less than 5%)...is that true?

    My DH wants to tell my mom that we are expecting twins at 10 weeks as it is her birthday then, but I am leaning toward waiting unitl Thanksgiving (as by then I will have completed my 12th week).

    I am torn on when to tell my mom. I agree, it would be a wonderful b-day gift for her to know, but the cautious side of me is afraid of getting her hopes up about twins when I am not out of the woods yet of having a VTS occur.

    Any thoughts/advice or experience with this is welcomed.

    Thanks,
    Donnie

    p.s. My OB agrees with my DH and that we should tell my mom on her birthday instead of waiting until thanksgiving.

  2. I have been wondering the same thing but I am pregnant with triplets. One of the babies is lagging behind.
    Can I ask you if both twins are growing at the same rate? If so, I would think that's a good sign...?

  3. I don't know if our experience is helpful because it may not be comparable, but in our case we started with quads that had heartbeats at week 6.

    Embryo D's h/b was always slower than the others and stopped in week 8.
    C started normal but stopped in week 10.

    As background, we had transferred 3 x high-quality 8-cell embryos and 1 x 5-cell. We figure D was the 5-cell.

    We wanted to share the news before 12 weeks too, so we played coy and just told the family that we were pregnant. We just didn't say with how many until after week 12 when we felt more confident. So we got to share two surprises instead of just one :-)

  4. Citro,
    I have had 2 ultrasounds: one at 7w1d and the 2nd at 8w1d. The babies at 7w1d had heartbeats of 120 and 135 and were measuring at 6w3d. The following ultrasound a week later at 8w1d my OB did not measure heartrate but said by looking at them the rates were at the normal pace and not slow (which would be concerning). The babies measured exactly a week larger at 7w3d and so according to my OB they are growing at the same rate and consistent with the previous week's u/s.

    Ruth,
    Thank you for sharing your experience and I am sorry to hear of the loss of the two. I hear you and have been thinking I should do the same. Announce the pregnancy to my mom on her birthday and then 2.5 weeks later after the next ultrasound (when I am able to verify both are intact and growing as they should) then announce that there are two.

    I will run it by my DH and see what he thinks.

    Thanks,
    Donnie

    I like this idea-I hesitated answering because I hate to be a debbie downer....we also had two to begin with and both looked great at 8 weeks....we had an ultrasound at the beginning of week 11 and baby B had quit developing and had no heartbeat. It occured sometime in the 10th week based on the growth we think-I have been told that that is unusually late....fortunately baby A went on to be just fine and was born healthy as a horse.

    I wish you the best of luck with the pg-hoping it's uneventful and that you hold on tight to both little beans. But I too think I would share the news about the pg first and wait till after 12 weeks to announce twins!

  6. I was just reading something today that said 21% can end in vanishing twin and usually by the 12th week of pg. I am 15 weeks and still afraid to breathe a huge sigh of relief. I think when I hear two loud wails,,,,,,,,,that's when I'll believe all will end well. Wishing you all success!

  7. Hi Ladies,

    Being pregnant with multiples is SO stressful in the beginning, particularly because you worry about things like VTS. I happen to be a VERY worrisome person to begin with, so of course being pregnant with twins after 5 years of IF and IVF was brutal for me in the early weeks. I asked my doctors so many questions about the liklihood of miscarriages, etc. Basically, they told me that every week after the detection of heartbeats, your chances of VTS or a
    miss of one or both babies is reduced. By 10 weeks, your chances are significantly lower. Can it still happen? Yes. But it can also still happen up until 24 weeks. But the chances are VERY slim. If I were you, I would probably tell your mom. It would be a wonderful surprise! And even better, than you have that extra comfort and support that is so necessary in the early stages of a multiple pregnancy. I know it's so hard- but try to relax and have faith that it will all work out! Before you know it you will be running around like a madwoman with those babies!
