Congratulations on your pregnancy Hindonly

At 5wk6days I had 2 sacs but only one heartbeat ...a week or so later 2 heartbeats and now 29weeks with twins. They were both 6 day old embryos (IVF) and conceived at same time. 'Naturally' some women either ovulate twice (and even over a few days) or the sperm and 2nd egg meet later so keep your hopes up.

Maybe too early to tell if they are identical - it is normal for babies not to be exactly same -though even identical.

Later one baby was 5 days behind the other in size and has still been smaller throughout my pregnancy

I haven't got my HCG levels here ... I will post them tomorrow.

Goodluck and hope Monday goes well for you.
