Biggest reason to miss a period is pregnancy but if you have not had sex, stress is also a reason and having a bad diet could contribute to that too. If you notice that you are skinny or your heart beats fast, it may be an idea to get checked out for hyperthyroidism which is too much thyroid hormone and causes irregular/missed periods.
The flaming hot stuff will not keep your period away, stress however does.
Stress can make your period delayed. I have been over a month late before, but eventually it came and is back on schedule.
Have you had unprotected sex? If you have, you could be pregnant.
If you have lost weight lately that could be another reason.
If you started your period for the first time in your life just recently then it is normal for you to miss periods.
From what you've said it is probably just stress.
if you are small or play sports that may be a reason?
You said you are skinny? Very thin women can miss their periods, because their body thinks that they are too thin to be able to get pregnant. Stress can also be a factor. Or maybe you are just very young and it's normal to have irregular periods.
stress or if u jus started
