Lose a stone in 3 months?

[Michaela0216]

is this possible? I am 5'3 and weigh 9st!! I was 7.11st at my lowest in the last year and a half since having my son, Im happiest at 8st-8.3st and would like to get back to this before my wedding at the end of May.
I've been slacking with exercise since September, I did so well before but then just decided to enjoy christmas and didn't go to the gym etc.
I still walk a lot 1-2 hours a day and am always running around after ds1 and 2, I don't eat too much and I'm not too keen on the idea of some fad diet so I'm thinking if I get back into the gym maybe some running and 30 day shred as I loved this last year.
Could I lose this weight in time for my wedding??
