I’ve looked up Vanishing Twin Syndrome, and almost every article I have seen said that VTS typically only happens during the first trimester of the pregnancy.
But here’s the catch: My mom didn’t realize or know she was pregnant with me until 7 months into the pregnancy. And when she found out, the ultrasounds did show two babies. Me and my twin.
If Vanishing Twin Syndrome usually only occurs during the 1st trimester, is there a reason why it can happen so late during the pregnancy, as in the case with my mom and my twin? Or is there technically another name for this specific situation?


Your mom said the doctor told her the ultrasound showed “two babies” but I had an ultrasound at 5 weeks and they looked at the tiny embryonic speck and said, “there’s the baby!” In fact no babies are shown in ultrasounds, only fetuses. But my point was, they may have seen one 7-month fetus and one little shriveled thing and said “there’s two babies.”
I guess it’s also possible she brought two babies to term, made a “Sophie’s Choice” to give one up for adoption, and didn’t want you to be heartbroken or afraid of being given away too. And since other people had heard about her being pregnant with twins, she gave you a story you could accept as a child.
And another possibility is that the doctor gave her anesthesia or rohypnol or something and took the twin to put up for adoption, telling her it was absorbed. She’d know she had given birth but not remember it was twice. It’s terrible but not unheard of.
You could ask her, if you feel you’re both adult enough now to handle the emotional implications of all the possible explanations. Remember that you can still trust her love no matter what, but she might not know the whole truth and/or might be ashamed to admit it.
Who is Sophie?
It’s a reference to a movie of the same name.
The gist is that at one point, Sophie is forced to choose which of her children die.
