In brief: It may be, BUT could be pregnancy

Pregnancy is certainly the most common reason for a missed period when sexually active.
An anovulatory cycle (your ovary just does not release an egg that month), thyroid conditions, rapid weight fluctuations, extreme exercise, stress, etc. Are all other causes that may be possible. If you are having sex unprotected, check pregnancy tests, otherwise if you miss your next one too, see dr. For eval.

In brief: Depends

It is normal to miss a period if you are just beginning your cycles (first 3-5 years), if you are entering menopause, if you are manipulating your cycles with hormones (eg birth control pills) or if you are pregnant.
On the other hand it can be a sign of trouble. If you can't explain your lack of periods, it is best to make a trip to your physician.

In brief: Depends

For women over 40, estrogen & Progesterone levels begin to fall.
This can lead to many variations in menstrual flow from what was "normal" for that individual-lighter, heavier, longer regular cycles, irregular cycles and missed periods. A missed cycle should still have pregnancy ruled out. A woman is not considered to have reached menopause until she has no period for a year.

In brief: Depends

A 28 day cycle is the “gold standard” for normal.
Normal length menstrual cycles can vary from one individual to another. A 28 day cycle will move across the calendar by dates because the only 28 day month is february. With that said, a true delay in menses in a sexually active female (regardless of age) needs to have pregnancy eliminated by testing. If that test is, negative see your doctor.

In brief: Anovulation

If you missed a period and your pregnancy test came back negative, then you most likely had an anovulatory cycle, meaning your ovaries didn't release an egg.
This happens from time to time but if consistent, see your doctor because you may have a hormonal imbalance. Consider a birth control consultation to regulate your periods and avoid unplanned pregnancy.
