I must have completely missed the "flutter" stage, because I've begun feeling little kicks and jabs from the little ones.
I kind-of thought that with twins I would grow twice as quickly (although that seems silly in hindsight because that would mean measuring full-term at 20 weeks) but my fundal heighth today measures 18 weeks which is only one week larger than my dates (currently 17 weeks). It will be interesting to compare fundal heighth measurements with twins to the normal measurements of a singleton.
I suppose I should measure my circumference too? Today I measure 34.5 inches (about 87cm). My pre-pregnancy waist was about 26 inches. I don't own a scale so I can't say how much weight I've gained; pre-pregnancy was 127 pounds. For the last couple of years I've worn only long skirts and dresses (with very few exceptions). This has made dressing my changing figure very simple with only my small fitted-waist skirts no longer fitting - most are elastic waist and fit just fine under the belly. Soon I'll have to get some maternity shirts though, or I'll be walking around with a long skirt, a little shirt, and a great big naked belly sticking out in the middle! Oh no, definately not my style!
