Ivf 2 embryo Transfer - my question is, if one sticks (which it has) what is the likelihood the other one has please?! I can’t seem to find information on it maybe I’m not wording it correctly.. both our embryos was graded very good (they actually advised us against a double transfer)

I have 2.5 weeks to wait to find out if single pregnancy or twins and the anticipation is killing me !! We will obviously be happy with one healthy baby and pregnancy of course!! but it’s my partner’s absolute dream to have twins (this is why we went ahead with the 2 embryo transfer even after they advised a 1 emybro transfer given our age (30&32) and circumstances (iv previously carried and birthed a child, my partner now has a low sperm count so we did icsi)
