vanishing twin syndrome

I'd like to tell my story before I ask my questions.

I tried to get pregnant for nearly 2 years, 2 miscarriages and 3 chemicals later on Christmas morning I found out I was pregnant again. I was 12 days past ovulation and my hcg was 88. Two days later it was 492, two days later it was 3400. So it was more than  doubling!

January 8th I had my first ultrasound. They said I was 5 weeks 3 days and the baby was small and the heartbeat was weak. (Devastated) I went home and thought the worse. I showed a friend of mine the picture,  and she said that it looked like twins.

January 9th I had another ultrasound by my endocrinologist  (I was seeing an ob and endo dr) sure enough he said I was 5 weeks 6 days and pregnant with twins. Two heart beats! Baby a was 5 w 6 d and baby b was 5 w 4 d. He said he thinks the other tech saw baby b but not a.

I kept seeing him every other week.

I also saw my ob and got another ultrasound by her. Again, one baby but it was healthy and had a strong heartbeat.

At the endo I had twins (my ob didn't believe me or my endo Dr because her tech never saw them). At 10 weeks my ultrasound showed one healthy 10 week old baby and a shadow where baby b had been.

He said that it may be a vanishing twin.

Between 12 and 13 weeks I had the normal ultrasound to check for downs syndrome and there was only one baby (anterior placenta) and she had a terrible time getting the heartbeat (it kept changing from 144 to 156 and back) she said that the heart may have a medical condition / complication that they would do a followup.

At my 20 week scan (it was actually 21 weeks 5 days according to my ob (who by the way is off on my due date by 1 week 1 day) the baby looked huge and the tech had a terrible time getting measurements. The 45 min scan turned into one hour 45 minutes and they couldn't get the heartbeat (he moved a lot!) And some measurements were weird.

Now, I'm between 25 w 3 days and 26 w 4 days and my uterus is 3 inches or more above my belly button, and I feel movement when I'm standing way way up high instead of down low. At my ultrasounds they said that his placenta is blocking the whole front of my uterus, and that a doppler would have trouble still finding his heartbeat (the drs doppler finds it but they listen way up high and it's 154. When the ultrasound techs get the heartbeat it's 144.

Questions:
1. Is it possible that the vanishing twin I had 16 weeks ago was just the developing placenta covering the second baby and I'm still having twins?
2. If so how can I find out?
3. Has anything like this happened to anyone else, good or bad, twins or not?
4. My daughter say there are two, I have dreams I am having two (b/g twins), and my neighbor (a nurse) used palpatations on my belly and found 2 hard spots she called heads one way way low and one way high on opposite sides. Is it possible his head is way down my my left ligament and his butt is way my by my right rib cage (2 or so inches under)?

Please don't think I'm stupid or just hopeful. This is my 8th or 9th pregnancy  (2 live births) and I've never experienced anything like this.

Not only am I a planner but I'm also a serious budgeter and I have 2 other children to think about. I want them to be prepared when I bring this baby(ies) home so they aren't stressed out and feel like I hid something from them. Also, I cant even leave the hospital without 2 safe up to date car seats and I wouldn't have 2 if there are twins and I don't know... it's driving me crazy! I'm not stressing about it, I know that's bad for baby but I still feel like I have the right to know!

Lifeisgood27, I'm not sure I understand what is going on, could you explain better?

I def dont blame u for questioning all of this. Esp if you're a planner this is tough. I wish you all the best, good health and a clear picture! I am not sure i have any answers, im preg for my first time myself... May I ask when the doc saw pics of your baby/babies, did it look smaller than it should for the # of wks pregnant, esp early on? I'm having that prob now. I'm 10 weeks and last week was told it was about half what it should be... prob not going to be so lucky (per docs prognosis but still hopeful) but going back this week to see if anything changes. Your story makes me wonder could i have twins or a similar situation? Sexy or anyone have any thoughts?

That sounds like a very stressful pregnancy. I think you should just relax and whatever the outcome, it was meant to be :)

Well if they were having trouble with the heartbeats and the measurements, it would make sense that your having twins. Try not to stress about it, go for a 3D Ultrasound!!

I've thought about a 3d ultrasound, but wasn't sure if they would be able to tell or not.

That's all I was worried about honestly being prepared. If I deliver twins (via c section) I'll have to have 2 car seats, 2 bassinets, double the diapers, double the wipes, everything! And currently I barely have enough for one. I'm not stressed as much as I'm angry that my ob seems to think I was never having twins... but I saw the heartbeats heard them! And now she won't any more tests to find out.i can't see the endo now since I'm past 10 weeks. It's just frustrating!

If possible, I'd go for a 3d ultrasound. Now that baby/s are bigger there would be a better chance at seeing if there are twins. I'd want to be prepared for having two :P and they're nice keepsakes.

I had a good friend who had an issue where one twin stole all the nutrients from the other,  the one didn't make it.  Anything is possible..

If I were u I think I would b wondering the same things.... I would guess that u have 2 babies in there cuz if they r having a hard time with measurements and heartbeats its what makes sense to me. I've never had this happen to me or anyone I know but I have heard twins can sometimes be tricky lol. If I were u of course I would want to know if I was having twins cuz u do need to be prepared for that! Hopefully they can tell more for sure soon, good luck!

Yes, of course. Anything is possible, but you sound like you should just take a breath and relax. If you have twins, then you have twins. If not, then you have one healthy baby. From where I'm sitting, it seems like you win either way. You seen unnecessarily stressed out about it.
Anyway, wishing you healthy, happy, beautiful babes! God bless!
