Hi and welcome - we had two transferred - 3 times - 1st IVF cycle - BFN
FET - BFN
#2 IVF cycle - twins - these were 6 days blasts though. I was older so they didn't talk me out of it.But it is uncommon.

I honestly don't know what the % is but in another group I belong to [16 mums - 20 babies born from Feb 2006 - July] - there were 4 sets of twins born. Plus another mum with identical twins on the way.

2 of ladies who transferred one embryo - had (or having) identical twins -one had ICSI 1 didn't (1 still pg) .

Three others of us had twins from 2 embryos.

I know many clinics refuse to transfer two to younger women because of the risks involved in premature birth.

In my group - three of us with fraternal twins delivered prematurely - one at 24.5 wks recently , another about 33 wks , me at 35wks 4 days via c/s (but due to maternal cholestatis not directly my babies)

The other identical twin mum was 37 wks - booked c/s.
The other ID twin mum is still pg.

These aren't really statistics but we had 4 sets of twins/16 mums - with one set identical from one embryo (natural miracle). Another mum also had twins but lost one very early about 7wks.

Of the other mums I can't remember who transferred two and who didn't.The IVF clinics were all over Australia, all ages too.So were our reasons for assisted conception - all these factors have to be considered for true stats.

I think it comes down to a personal decision I love my boys and am so blessed with two -because they will be our last and grow up with each other - I doubt we would have tried for #2 IVF baby otherwise.We had no frozen embryos left either.These two were our last 2 emvryos on a fresh cycle.

To be honest - my boys are only 6.5wks so I can't say how hard it is or isn't.It is all I know.Our only other child was adopted at 13 months (now 13yrs). So we missed his tiny baby stage.

I had my mum here until last week too.Plus a very supportive husband.

Though reading my twin books,and Multiple birth literature it is very difficult and stressful the first 12 months and after that I am told it gets easier .

I also know several IVF mums who lost one of both babies due to premature birth.

It is very confusing.I hope you come to a decision that suits you and your husband. Wishing you a world of luck in your baby quest.
