Suspecting twins...sort-of update post #9, new question post #15 - Page 2

post #21 of 43
Has the OB tested for AFP? I think that's what they called one of the blood tests they did. I had trouble with my OB over it, they didn't get the results to me until after I had my 19 week u/s. Anyway, twins will give you a different reading than singletons. Might be another way to prompt a u/s.

BTW - until my run of the mill u/s there were no signs I was having twins. Sure I had raging morning sickness, but no one guessed it was two. We heard a heart beat early, but like you, once the nurses found one heart beat they quit looking. We were bowled over at the u/s. Looking back, the only real sign of twins for me were my breasts. Pretty much the minute I got a positive preg. test, my already large-ish breasts doubled. I joked that I could feed armies. Turns out that's what I would be doing!

Nope. I actually turned down all the genetic screening and related tests. I have no risk factors, so it didn't seem necessary. I'm also no longer with that OB, so it's all moot anyway.

nd_deadhead -- It would definitely help to have two parents home every day if this is twins! Thus one of the reasons I'm going nutty...Dh would have to start planning now to find a new job in this area, and it's not likely he could find one that pays as well as his current one. It would require major lifestyle changes, above and beyond all the adjustments to having two new babies in the house.


I have a call in to my new midwife, and I think I'm going to ask her about this when she calls back tonight. She has to confirm my first appointment date anyway (which is now going to be next Wednesday unless something comes up) and she's much more likely to listen to me than to blow me off like the PA did.

My AFP results were completely normal, I was only measuring a few centimeters ahead and my doctor only found one heartbeat (though once he said that there was an "echo" - ha!). So . . . sometimes you really can't tell there are two in there without the ultrasound. I promise you, two came out!

(anyone know, btw, if AFP results are more likely to be normal for MZ twins? maybe especially if there's just one placenta? maybe it effects hormone levels less than two? I've been wondering that for awhile now . . .)

Vanauken: I don't know for sure, but I think MZ twins in the same sac would be more likely to have singleton-like AFP results. For the various early screening tests (including, I think, AFP) one of the main things they're measuring is HCG (which is unusually elevated in the case of Down's for example). Much of the HCG is produced by the sac or placenta, so it would make sense that MZ twins wouldn't have much higher levels than a singleton. At least, this is the case in first trimester (so, while DZ twin mom's tend to have high beta HCG levels, often a tip off that there are twins in there, in the case of MZ twins in the same sac, it's more of a surprise due to lower/normal beta HCG levels. But I don't know for sure if this changes later on as the babies get bigger. If the MZ twins were in separate sacs, placentas, etc. then they'd be the same as the DZ twins in this respect.

At 14/15 weeks i was measuring 18cm, almost up to my navel. I suspected by 10 weeks because I was already half-way up to the navel by then.

Thanks for the explanation/confirmation . . . it fits right in with what I was wondering. I hadn't heard that the sac affected hormone levels too; that's really interesting.

Thank you so much for all the input, ladies. It's been helpful (and, as an aside, interesting to hear about the AFP results and hormone levels stuff!)

After talking to the midwife last night, we're definitely going to have my first appointment next week, and if she thinks it's at all indicated, I'll be having an u/s sometime before Christmas. So, it looks like I have a gameplan now, and only a few more weeks of going nutty until I know for sure either way.

Just agreeing with pp's about not counting on the Doppler to find two heartbeats

Even after we found out we were having twins (18 wks) and they were looking for two hb no one was ever confident they actually had found two seperate ones. My dz twins had the same heartrate or were within a couple beats of each other every time. It made for some long nst's and a lot of very surpised nurses and techs when they weren't mz

Well, the midwife appointment last night pretty much confirmed what I already knew. Even for a second-time mommy, I'm measuring quite a bit larger than I should for my dates. I also had, as she put it, "heart tones all over the place."

So, I finally go in tomorrow for an ultrasound. I'll be able to settle this for good by the end of lunchtime. And if it is actually twins, I'll probably be in shock for weeks.

How exciting! Let me tell you at least you're suspecting twins so it'll only be about 90% shock

If twins, will your MW still be able to attend your birth or will she have to transfer care?

Two weeks ago, at 25 weeks gestation, we discovered that I am carrying twins. I had been feeling "big" but my homebirth midwife (a mother of twins herself) didn't really consider it a serious possibility. (Plus, everyone assured me that you "pop" sooner with the second.) I had been measuring normally for a single baby until right before Thanksgiving. When I expressed concern about my size at that time, her thought was that perhaps I had too much fluid or possibly gestational diabetes. Palpation and a doppler check for two heartbeats were inconclusive. My uterus was measuring 2 weeks ahead which also wasn't a clear sign. I agreed to get an ultrasound and it was there that we had confirmation that, indeed, there are two!

I have many friends who thought for sure they had twins because they just seemed so much bigger the second time around. While I am no fan of ultrasound (I didn't have one with my first pregnancy), I am relieved to know how many I have. I think you will find it to be very helpful in your case too!

Good luck!

Good point!

If it is twins, she'll be able to attend the birth. Whether that's what actually happens will probably depend on several factors. I'd prefer a homebirth, but it would be a HBAC and her first twin birth as primary (she's still a student, and I don't know yet how much experience her preceptor has with twins) so we'll have to see what everyone's comfort level is, kwim? If I go with an OB and hospital delivery, it'll be an automatic RCS. Not my first choice.

Thanks for the luck, ladies. I may need it.

Can't wait to hear the news.

At my 12 week (technically I was 11w2d) prenatal OB appt, doc said I was measuring big. But he said the same thing with my 5yr old singleton, even had an u/s early on with him to rule out twins. Big babies run in my family. So he shrugged it off. Then he pulled out his Doppler and couldn't find any heartbeat. He assured me there's really only a 60% chance of locating a heartbeat at 12 weeks. So he ordered an ultrasound just to be sure. 2hrs later I was on the ultrasound table, and this is what we saw:

I know twins isn't very desirable for you. It is a complete change of lifestyle when you have more than one. But I know you'll feel blessed regardless.

Can't wait to hear the news!!

Please let us know as soon as you find out! I can't wait to hear! :

If you are pregnant with twins, are you still planning on homebirth? I would say go for it! It was and is amazing!!

This has been the weirdest day ever. Ups, downs, everything in between.

It isn't twins. My midwife, the tech, and I were all shocked at that, we were so sure. But anyway, it's just one healthy baby measuring 17w2d, estimated at 7 oz, and very wiggly. Good placenta and placement, everything normal, including fluid levels. Nothing at all to indicate why I'm measuring 5 weeks ahead. The only possible explanation is that he likes to hang out as high as possible, tucking his itty bitty back into my fundus.

Thanks for putting up with me and giving me so much support and info. I'm off to get a nap. I think I need it.

Congratulations on the healthy baby!

Aww, just one means you're going to get twice as much sleep as the rest of us

Yeah for one baby with some extra room for doing somersaults!
