Thank you for your replies ladies.
I was terribly sick ALL DAY yesterday and badly fancied a chinese for dinner (our set menu contains a prawn dish) However, during a conversation with my pregnant friend (due the same day as me!) she was virtually telling me off for even mentioning prawns!!!
I didnt end up eating any with my dinner, not because i was worried, but because i didnt actually fancy any in the end!
And bizarrely, the chinese managed to settle my tummy. I had no more sickness .... til this morning!
