period twice in a  month?

When under alot of pressure and stress I've had two in a month.  Usually one is really light.  But it's always best to go and see a doctor if you feel something may be wrong.

I agree with Heather, you should see your doctor.  I had a female friend who had "irregular" periods where she wouldn't have a period for months at a time, but when her period came it was just a normal 1 week thing.  The irregularity may be normal, but the 3 weeks of menstruation is what I would check about.

I just found out that Canadian scientists have found that a few women ovulate twice a month and others have the biological potential to do so. Hope this helps.

It is perfectly normal to have irregular periods.  If you have alot of stress it happens, or if you exercise too much, or don't eat properly, or you can be perfectly healthy and its genetic.  Ask your mom if she was that way.  It is slightly possible it is problem like cysts so you should definately talk to your doctor.  She'll be able to figure out if it is a problem or if it is natural for you.  If it really bothers you, you can go on the Pill, which will make your periods lighter and as regular as clockwork (I literally get mine at 9am on the Wednesday they are due!)  So, there's nothing much to worry about since you are young, but talk to your doctor and go on the Pill if it bothers you alot.

Sometimes you ovulate twice in a cycle. It's not a regular thing, but it does happen. As most women ovulate 14-21 days into their cycle, you shouldn't be getting pregnant. Still, go ahead and buy a pregnancy test kit. They are pretty accurate. Most likely you aren't pregnant though. The double ovulation thing isn't the norm, but it does happen. I guess I keep saying the same thing. Sorry. It can't hurt to check. It's not that expensive.

Bleeding for longer than your normal period is not a good sign. There is something else going on, could possibly be a tumor. Go see a doc as soon as you can.

Here is a list of causes of irregular periods.  Stress is definately one of them, even if you are extra happy in your new marriage that has nothing to do with stress, you can stress and still be happy.  But read this and I hope it helps, but suggestion if it doesn't change in about a month make an appt. with your gyno because it could be something more serious.  Good Luck!!\n\n\n\nCauses of Irregular Periods\nIrregular menstrual periods are usually the result of hormonal signals that have been thrown out of sync. In order to produce a period, your body makes hormones, like estrogen and progesterone. These hormones are kept in the hypothalamus, pituitary gland, and ovaries inside your body. In order to trigger ovulation and menstruation, these parts of the body need to send signals to one another. Sometimes, these signals get crossed or skipped, causing irregular periods.\n\nBut what causes these hormone signals to get out of whack? Well, there are actually a number of things that can easily cause your hormone levels to change.\n\n\nPregnancy: If you are pregnant, your body will begin producing different levels of hormones. This will cause numerous pregnancy symptoms, including an end to your period. \nStress: Stress is a common cause of irregular periods. If you are fatigued, worried, or anxious this can cause your hormones to become unbalanced. \nDiet: A poor diet or extreme weight loss or gain can also affect your hormones. Women with anorexia or bulimia often have no period or irregular periods. \nExercise: Intense exercise can wreak havoc on your body, often causing irregular periods. \nMenarche: the cycles after a girl’s first period may be irregular for some time. It can take up to 3 years to get regular periods. \nMenopause: Menopause causes changes in your hormone levels, and is often signaled by irregular periods. \nHormonal Birth Control: Birth control pills and irregular periods sometimes go hand in hand. It can take a while for your body to adjust to the new levels of hormones delivered by hormonal birth control.

Yes, its common.  Sometimes, when my period is done I bleed just a little bit.  Nothing to worry about.  It seems like it never wants to leave us. lol

You need to go see your gynecologist, because there  could be some  \nfibroid tumors, endometriosis, ovarian cancer and even uterus cancer.  That happen to me almost 4 years ago come January.  The first one was about 1/10 and the second one was about 1/21.  I went to my gynecologist and that June I had a hysterectomy, of course I had fibroid tumors.   Get checked out.  And to ease your mind a little a lot of females go through that change when your period is just changing cycles.

As people have said before, stress but what hasn't been mentioned is that weight loss can do the same. I recently lost quite a bit of weight and until I gained it back my period came every other month. If this continues on to your next period its a good sign that you have lost too much weight and is your body's way of saying you have to gain it back. Whether stress, weight loss, or something else, good luck!

relax...that one inch piece of blood is most  likely a blood clot which is normal...if you're this unsure about your period you are probably younger and just starting your period...which will be irregular and last longer than normal...i once had a heavy period that lasted for 2 weeks and the i went to the doctor and they said it's normal you're body's just adjusting...so don't worry...

Yes, this is normal.  Sometimes your cycle just changes like this.  It can be for many reasons for example stress, exercise, weight gain, even diet change.  I wouldn't worry about it.

Stress and weight changes can cause you to skip periods every once in a while. See your doctor if you think it's something else.

Irregular periods are just irregular periods. Are you asking if you are pregnant? Either way-SEE A DOCTOR!!!

During PMS or during your period?? Either one is ok and perfectly normal.

it happens to many women. sometimes we have irregular months, caused by bad nutrition, stress, or maybe even nothing.\nif it bleeds for a couple days, you are fine. if it lasts longer, or if it keeps happening, then that could be bad.\n\ni would say just relax and enjoy your thanksgiving, it's really nothing :)
