I know this is nasty,but my menstrual period started when I was 11,now I'm the next age-12!my period hasn't come on in months and my stomach has been hurting occasionally at random times,and I know I'm not pregnant,:eek:

It can take quite a while for your periods to regulate in the beginning.
If you are having severe cramps then it is best to ask your doctor.
Nothing to be embarrassed about, trust me they get worse questions :)

Lol thanks
