i am 29, first pregnancy, went for first scan at 13 weeks on monday to be told i am having identical twins! none in either families, i seem to just be the lucky one! i still look like someone has shoved something sharp up my bottom. shocked cat comes to mind. 
i am 5ft 10 and and before i got pregnant and in the early weeks, i struggled to get over 9.5st (i am a freelance spin instructor and do 7 classes a week). now i am nearly 11st, but apart from my huge boobs, i am not showing at all. still in my size 10 clothes and even able to suck my tummy in super flat. where on earth are the twins growing?!
feel completely normal, not sick, not tired, not overly hungry and wondering if there is enough food in the world for the 3300 a day calorie intake i am being told to consume.
can anyone impart some widsom and experience on me?! feeling rather like a fraud, as apart from my hilarious scan pics (twins lying down side by side facing one another, appearing to be arm wrestling), i have nothing to show for my secret!!
