How about 'The only woman to ever be pregnant' mum to be.
She appears to have all the symptoms of a heavily pregnant woman - tiredness, constant need to pee at all hours of the day, constant feeling of sickness (even though she has never been sick yet) and an overwhelming need to "nest" not to mntion utting on nearly a stone in weight
And she is only 8weeks gone.
Just wait tll shes twenty five weeks gone and can no longer bend down to tie laces, shave legs, pull up socks etc etc then she can complain
Acting like shes the only person in the world who has ever experienced pregnancy. And worse ye, is one of the mums who think she still fits in her size 12 (pretends they are size 10) jeans, with rolls of bulge everwhere, its not nice.
