Question:
Ummmmmmmmm?
what is another reason for a girl to miss her period (besides being pregnant) ?
Answers:
"Stress, increased exercise, weight loss, or illness" More than likely she just missed a period for no apparent reason. It happens to every body. Relax. She should go to a doctor if she misses next month.
If she has recently just started getting her period, it takes awhile for a cycle to regulate. In that case she should expect irregular periods for up to 2 years.
