WOW Chard and Hairspray, look at you go! I genuinely can't imagine losing an entire stone in a month, that's such an incredible achievement.
Spurious again, the dangers of daily weighing
Please don't get downheartened about it, a fast day will have had an impact, there's just no physical way it can not, it just takes a while to settle down.
I sometimes find after a fast day - or more to the point after a bunch of golden activity - I get a disappointing scale result, but then as soon as I eat properly I finally manage a proper poo, and wonder how much of the weigh-in was just sitting in my gut 
Arsey I have a wedding on 25/3 too - maybe it's the same one! 
Speaking of which, where's LegendOfBeans gone? Her wedding day must be right around the corner?
