Vanishing twin syndrome - anyone else experienced this?

[Natalieand]

So I'm 28+4 now but early on in the pregnancy the sonographer said I was having non identical twins as there was two sacs and two fetal poles. When I went back for a re scan a week or so later only one sac was left with a baby which is now my 28+4 bump, but I just can't help but wonder what if? If that makes sense? Could I have done something to make the other one thrive? Or what sex would the other have been (current bump is a boy) isit selfish of me for thinking this and should I just be great full I stil have a healthy pregnancy?

I had a scan at 9 weeks that showed a very early gestational sac - though nothing else so probably didn't develop far. Am now 26 weeks. I did have the odd thought about it - I am having my second son and did wonder if the 'other' baby was the girl I'll probably never now have. But I haven't thought about it much - probably because at the stage I saw it, it was immediately clear that this was an unviable pregnancy so it was always about the healthy fetus. I think that being told initially it was twins is harder.

Feel what you need to feel, it is normal enough to find it strange and certainly not selfish. But remember that this probably happened quite often before scans got so good - in a way, it is the downside of technology that we see so much of what might have been xxx

I already have a 2.9 year old dd so I will have one of each so in that sense it doesn't bother me it's just like u say I kinda wish I never knew cos I woud never miss it as I didn't have bleeding either so if I hadn't had the early scan I would be none the wiser as the sac and fetal pole were re absorbed appArently xx

I would talk to someone about how you feel. I lost a twin and it never goes away but you will tie yourself up in knots thinking what if?
