That is not uncommon when you are about to start your first cycle. It could start next week or in another month or more. As to what to expect, well that is different for everyone. Some girls get cramps and others don't. Talk to your mom about her first period as you will most likely have similar experiences since you are genetically linked. The best thing you can do is not fret over it and let nature takes its course.
