Scream, I too would have been in floods of tears if I was told I couldn't have the scan, with everything you have riding on it. I'm so pleased you can have it after all! I'm 28 too and I had the MMR in Primary 7 (age 10/11). I thought the MMR replaced 3 previous individual jabs, though. I did have mumps when I was 5, though, so maybe not. You might well be okay, though - I had it and my sister didn't, despite us sharing a room and going everywhere together, so you might be lucky.
Cakes, I'm sure I read somewhere that the bad press was all scaremongering and there was no evidence that the MMR caused autism. Does anyone know for sure?
Biscuits, I haven't got a scar from the BCG either! I thought it was the smallpox vaccine that left a scar. I've not had that - too young.
Dream, have a bf tip for you from my mum - she says if 1 twin wakes up for a feed, wake the other up and feed them too or you really will be feeding continually. You probably knew that already, but thought I would post it just in case.
