Four and a half months I replied.
"Ah but no" she said .... "How many weeks?"
OMG I didn't have the foggiest, gave up on that a while back! Not wanting to show my ignorance the lap top went flying as I reached for the calendar with pen and paper ...
Had to try and work it out before she realised I was missing from chat ...
She's 19 weeks ... errr 19 and a half weeks, well 20 weeks on Monday, but not 5 months, well not yet. Confused? Join the club.
I'll stick to months I think!
