Welcome enchanted! Good news!
I am still sick and tired in the afternoon. I'm lucky - never throw up -- but a positive epidemic of hideous burping instead. Like comedy burps. Many sympathies to those who are more seriously afflicted.
Reasons I think it might be twins: I am about seventeen times as tired and ill as I was with my first child - as in I MUST have a nap EVERY DAY and sometimes twice, despite sleeping well; had a very strong positive pregnancy test very early; my belly is really sticking out (I mean come ON) and I've gained about 10 lbs (not surprised as I am constantly hungry). I have a twin brother and sister and my husband's dad is also a twin. But nothing is sure until the scan -- it could just be a very hungry big baby I suppose.
At least I am over the hugely vivid dreams and the hot sweats at night. They never tell you about that, do they?
