If you tend to slip to the front of the saddle, or if your hands have too much pressure on them, raise the saddle's nose a bit. Girls are shaped different from boys. Most of us know that, but bicycle makers don't seem to. Sexism in cycling ensures that most bikes are OK for boys and uncomfortable for girls. That's because the frames of most bikes are built to fit average men, not women.
Women tend to have longer legs and shorter upper bodies than men of the same height.
As a result, a frame that is the right height for each will have a top-tube that's too long for the woman if it's been designed for a man. Thus women will tend to have a longer stretch to the handlebars, and a greater propensity for numb hands, sore shoulders, and sore neck. The easiest adaptation for this problem is a handlebar stem with about an inch shorter extension than is standard on a man's frame. But since that correction may have already been done, don't race out for a new stem unless you're having numb hand problems with yours. But do pay attention on the training rides.
