AFP is not a test that picks up twins. IF the numbers come back higher than normal it could point to twins but it does't diagnose them. The AFP is has a high false positive rate so it is a very inaccurate test. The only way for twins to be diagnosed is an u/s. At 32 wks the tech would have seen an extra sac, placenta, two hb, and way to many heads and limbs for one baby, so I am sure that it is only one, after two u/s.

I would think that by 32 weeks, if you were having twins, it would have been detected...either by sono or heartbeats. And what your belly is measuring could have pinpointed it too. Did you not have a gender scan around 22 weeks?

Well, I looked at the AFP test results again, and I am sorry, what I posted was a typo.. it DID say, "This patient is having twins", however, below the test results saying i am having twins, it says it was detected through u/s @ 15 weeks. So I am wondering why it wouldn't show up now?

32 weeks is quite far along -- do you feel movement that seems to be from 2 babies? I am having twins -- and have had such a weird feeling that there was a third one -- but I am almost 28 weeks along and only feel movement from two. I'm thinking maybe I had a vanishing triplet before I knew I was pregnant -- hence the intuition....you might have had a vanishing twin -- just a thought.

Question@Amanda: Can a twin vanish after 15 weeks?

Jessica usually after the 1st trimester the vanishing twins don't absorbed completely. I'd have to say if your Dr. didn't say it was specifically twins then it isn't. Your care would be drastically different than a singleton. What would be the point of not telling the mother. At your various u/s did they label you u/s pics Twin A and Twin b and give different measurements? A twin u/s usually lasts over an hour because they have to take two separate measurements.

I think it's possible for a twin to be reabsorbed even as late as 15 weeks -- but don't think it's the norm. However, maybe it happened earlier than 15 weeks but your system was still being affected by the lost twin at that time -- hence the twin test results....or it could have been nothing, just a high result for no apparent reason.

Oh, ok, because the AFP results didn't pick it up... it said the sonogram picked it up... But then again, it could have been just an error... The AFP results were normal.

I'm confused...did you have an u/s at 15 weeks? I thought you said you had one at 9-10wks then one at 32 weeks. Only an u/s can determine how many babies there are. The chances of having a normal afp test when pg with twins is low.
