Periods months apart?, starting to worry. Options

[kimmytree]

I'm 17, and I first started when I was eleven... so shouldnt my cycle be normal by now? I havent had my period since the beginning of January. And before that, the last one was June... so I went SEVEN MONTHS without having one. So I'm guessing its going to be seven months between my last period and my next. At one point, I guess at around 12, my periods were normal. Then over the years, they've become more and more irregular. Up until the one I had in June, they usually came every three months.

I'm seriously starting to really worry about this. Everytime I go to the doctor, they test my urine/blood, and everything comes back normal. And my mom claims that there's nothing wrong with me, and that I should be normal eventually. But I'm worried that there's really something wrong, and my mom's just not telling me.

What might be wrong? And what if I never become regular? Will I have problems having children later on?

If you are not pregnant, other causes of missed or irregular periods include:

* Excessive weight loss or gain. Although low body weight is a common cause of missed or irregular periods, obesity also can cause menstrual problems.
* Eating disorders, such as anorexia or bulimia. For more information, see the topic Anorexia Nervosa or Bulimia Nervosa.
* Increased exercise. Missed periods are common in endurance athletes.
* Extreme emotional stress.
* Travel.
* Medications, such as hormonal birth control methods, which may cause lighter, less frequent, more frequent, or skipped periods.
* Hormonal abnormalities, which cause fluctuating levels of the hormones needed to support menstruation.
* Illegal drug use.
* Problems with the pelvic organs, such as imperforate hymen, polycystic ovary syndrome, or Asherman's syndrome.
* Breast-feeding. Many women do not resume regular periods until they have completed breast-feeding.

Premature ovarian failure is when you stop menstruating before age 40. Surgery, chemotherapy, and radiation therapy to the abdomen or pelvis may cause premature ovarian failure.

It could be polycystic ovarian syndrome is what I'm guessing.

You could try contacting your doctor (or whoever runs your tests) when your mom's not there and asking them if there's anything wrong with you. She wouldn't be able to stop you, and it's only right that you know what's going on with your body if there really is something wrong.
