I'm 13 and not had mother natures monthly gift yet is it normal?
Yes it's normal. Some girls don't start until they are 16-17. Just be happy and enjoy life. It'll happen when it's supposed to, and when it does, you'll wish it didn't.
It isn't something to be concerned about. Some just take longer then others for example my sister started at 11 while I started at 15.
It's totally normal. I got it at 12, yet my cousin is 16 and is yet to get her period. Enjoy it while it lasts.
