Why no period?

Melissa

Hi ladies out there! I wanted to share my concerns about the fact that I haven’t gotten my period for 2 months in a row. I am sure I’m not pregnant for I’ve taken several tests. Why could this be happening? Does this happen to you too? I’m 23 years old and this has never happened since the first time I got my period at 13. I’ve always been regular. Please HELP!!
