For women, the many hormones throughout the body, daily life, stress, changes in sleeping and eating patterns, menstruation, pregnancy and the overall reproductive cycle, the possibilities are endless with regards to differences and abnormalities in the menstrual cycle. The good news is that irregular periods can occur at any time for a variety of reasons, and the condition is a very common one.

A regular period for most women who are regular (every 28 days) typically last anywhere from three to seven days. In this sense, a one-day period is not usually normal for most women. That said however, since many things can cause menstrual irregularities, a bit of irregularity can and is normal over a woman's menstrual cycle.

As such, you could also wait and see if the irregularity continues onto the following month. You could also see your doctor as soon as possible. However, in the meantime, I would recommend taking as many notes as you possibly can as you experience this, so as to better present your condition to your doctor.

Your notes should include details including but not limited to: When did you notice the one-day period? Consistency/texture? How long are your periods usually? Was your last period on time/regular? What was the length and flow of your last 'normal' period? And so on. This will help your doctor decipher the cause.

Possible Causes

Although the list of possibilities is a long one; a very common reason for a period that lasts one day for many women is pregnancy. It is important to be aware of the fact that although you "had a period"; often times and in cases where it is such a brief period, it is actually the "signal" for bigger things to come. In other words, you could be very pregnant. If you had unprotected sex in the last 3-5 days of ovulation, pregnancy is definitely possible. This could be implantation-related bleeding. Furthermore, many women do "bleed" during pregnancy.

Other conditions that disrupt the regular patterns, and schedule of the menstrual cycle, include but are not limited to: sleeping habits, weight changes, stress, a poor diet, over-exercising, thyroid and other hormonal imbalances, pelvic and other infections.

Your abnormal or menstrual irregularities could also be stemming from your ability (or lack of) to ovulate. It could also be from uterine- related changes such as a polyp as well as pregnancy. With this many possibilities, it is easiest, wisest best, and safest to see your doctor.

Points to Remember

"A period does not always mean no pregnancy" and a "pregnancy does not mean, there will be no bleeding until birth." This one-day period could be left-over or residual bleeding from your last period and/or implantation. Going forward, pay extra attention to related details. Also, keep a log book. Detail changes, your feelings, and physical experiences (e.g., discomfort, cramps, nausea, headaches). If you suspect pregnancy, get a pregnancy test done, and please contact your doctor immediately to confirm or rule out your suspicions.

Be Safe

At some point in every woman's life she will experience an "abnormal" period, and it is not at all unusual for the occasional irregularity or change in her cycle. it is important to determine why the changes are happening, however: Is this stress-related? Pregnancy? Menopause? Eating habits? How about exercising? In order to figure this out, keeping a log will help to unravel this mystery, and seeing your doctor as soon as possible is critical. since he or she will be able to evaluate the situation and advise accordingly.
