Could you add a "You are XX weeks pregnant" to this page (possibly with a link to the relevant pregnancy calendar page)
I know other websites have this on their due date calculator.
This is my fourth baby and I am not quite so obsessed as a first time Mum with pregnancy tracking, so frankly I am not keeping track of how many weeks I am. My due date is 17 September you see, I know I'm somewhere mid-20 weeks pregnant but not certain exactly how many weeks.
I shall have to leave the MN site to find out - which seems a needless way to get a user to navigate away from the website when it would be simple to put the answer on here somewhere.
