This may seem like a silly question and for that I apologise, but I am reading up the duff and trying to work out which week I read. I am supposedly 10 weeks 1 day, so does week 10 or week 11 correspond with this??? For those that have read the book, I know the length ruler at the start of each week symbolises how big your baby will be, but is that at the start of the week or the end?

You wouldn't guess I have done this before, I have really confused myself.
