Sac issues- for Ghost or anyone

[Love Bug]

During my second u/s we saw three sacs, two of which were same size with fetal poles. The third one we couldn't get a good picture of. We went fir our third u/s yesterday and saw the same two with little babies and heartbeats. Again the third was smaller, and it had something in it, it just didn't look like a fetal pole and there was no heartbeat or blood flowing.

My question is three fold: is it possible for an embryo to be behind and to "catch up" later; if there is would that lead to developmental issues later in life; and does a mc of one embryo effect the other two?

I have had no bleeding or spotting at all. Would the sac just go away after a while?

There's a good chance that third one will not make it. That is not all bad news, because a twin pregnancy is much less risky than a triplet.

I have not seen any studies relating early detection of a fetal pole to health of the child at birth and afterward. Probably it has been studied.

From our data it looked like early loss of one embryo had nothing to do with loss of any others, in twin pregnancies. I have not studied triplets. I believe other researchers have concluded differently, finding the loss of one increased the chance of losing the other. If so, we did not see it in our results, so such a relationship, if any, is probably not very strong.

I don't know what happens to a tiny sac like that. I have heard (from a physician) that they can be "absorbed", but I have not studied it in any detail.

Sounds like you have a great set of twins! Possibly a triplet. Also sounds like your maternal instinct to worry about them is already hard at work. Trust me on this one - you will worry about them for all the days of the rest of your life. He's driving where??? She's dating who??? He's investing in what??? It never ends. Welcome to the world of parenting.

I had this same thing with twins, not triplets. They said the sac would get reabsorbed. I agree with Ghost, its sad, but much healthier to be carrying twins vs triplets. Triplets can have a lot of issues if born early, and many are...

In my case we saw the one that was behind actually develop a heart rate. It never looked normal, but finally stopped developing at 8 weeks. We could still see it in the ultrasounds, squishing up and such and finally did disappear around 12 weeks.

One thing you will want to do if you are planning amnios and esp if you are going to do a CVS...Make sure the doctor doing those procedures is aware the this embryo (if indeed it does not make it). They will want to be careful not to accidentally get cells from this one and then give you the news that there are chromosome abnormalities. Most likely, this one has some chromosome problems that are causing it to not develop normally. So you definitely don't want to be looking at the results of your tests and see something bad, when really its cells from the embryo that did not make it. My RE made sure I was aware of this and I did have a CVS and the doctor was careful to avoid the placenta of the embryo that has passed. Unfortunately in my case that pregnancy did not work out even though the other twin was normal. But my issues were related to a disease I have and not related to the twin that did not make it.

I am now 33 weeks with a subsequent IVF! Good luck and let us know what happens. I know how it feels to want that one to make it, but also worry about it making it with issues. I think its likely to not make it based on what you said, but you never know. Twins will be handful anyway and CONGRATS btw! Its amazing how many sets of twins are showing up with all our IVF-ing!
