NO!!!!!! Don't WISH for it!
I get regular periods and they are NOT fun.
You only heard of cramps, you have no idea how they actually feel or how horrible they can get...this you will NOT like. This, you will be wishing you had no period again. Also, not only cramps, other things come with periods. They can make you tired, irritable, naseous, headaches, achiness, bloat, etc. Not to mention constant monitoring to make sure you aren't bleeding through your clothes.
Anyways, you will get it when your body is ready. Some girls haven't gotten their period until they were 18. One of my old friends didn't get hers until she was 16. But, your normal and there is nothing wrong with you. Just wait for it to come. And for that matter, how would the other girls know if you got your period if you didn't tell them? A light doesn't just come on saying "woman with period". Maybe you should be hanging around people who aren't so immature. Those people don't make good friends, so ditch them.
