I would leave everything for a few months. Chill. Enjoy your current weight. BUT you need a "klaxon". Make sure you know this (or maybe 1 or 2 pounds higher) is your maximum. If you get above, say 11st 8lb, then you need to watch what you eat for a week or two until you are back comfortably under 11st 6lb.
I went for years around 66/68kg. Not massive but I knew I was not 100% happy and BMI was 25/26ish. I lost 10kg just by coming off the pill. (Actually about 8kg was probably coming off the pill, the other 2kg was spurred on by the weight loss if that makes sense...it was dropping off so I also upped the execerise and MFP for a month or so.)
At my lowest weight I was 57kg. And possibly a but scrawny round the face. 58/59kg is good for me. I am currently 60kg, but I am coming down again after hitting 62kg after Easter. 62kg is my klaxon moment. The, "OK Jimmy, drop the extra piece of toast, watch the biscuits, run an extra 5K this week" weight. I groan when I hit it, but a few weeks of taking care (not dieting by the way, just watching the carb extras) and it drops again.
I also know I put on that extra 2kg during school holidays (term time only so am off with the children, snacking, icecreams etc). I tend not to worry about it and know that I can drop it again once term starts.
Celebrate what you have done. But (sorry) just know you need to know when the relaxing into your new weight has to end (your 62kg klaxon) so you don't end up back where you started.
And in a few months yes, maybe think about bringing the weight down again. If you want to.
