Hi Mina
One thing I used to do when I got a stich was to do 3-4 large exhales 3-4 seconds apart and when I say large exhales you really want to empty your lungs completely.
Also while the stich is running off just gently ease of the gas a little and concentrate on running smoothly (as if running on ice).
I used to stitch up when running downhill as the impact combined with my legs running away from me triggered them for some reason.
Hope this helps.
