Congrats Kasha! I'd say you can relax now but I have been there and you don't really relax just cos you had a good 12 week scan. But it's better than a bad 12-week scan so try hard to relax!
Welcome rainrain, I think your symptoms going a bit better at this stage is normal, I remember I felt a bit less tired and sick around that time, and by 11 weeks I felt hugely better - thank goodness!
Ronshar - twins! Oh yes I felt terrible in first trimester, didn't feel hardly any MS with first baby that MC'd at 10+4 but this time around it was awful. I felt like I had lived on McDonald's for six months eg totally devoid of any goodness/nutrition inside me. The babies were taking it all!
I'm still having my hair dyed and I've got half a bar of Dairy Milk to go home to tonight - yum! I even treat myself to half a glass of white wine at the weekends now and it is SO GOOD! I figure with two babies in there the alcohol is shared between them
Makecakes - can't say I can say for certain that it feels like there are two babies in my tum. Obviously I will probably be getting double to kicks but often it is not clear which baby it is. I do get kicks ALL the time though, so I think while one is sleeping the other is awake!
