Q: My periods come every three to four months, what's wrong?
A: There is one important word missing in your description, and that is "ovulation." Your regular periods depend on regular ovulation, and there is a chance that you don't ovulate (anovulation) on your own. First, your doctor needs to find out if you ovulate. Then, the causes of your anovulation should be evaluated. You can then get treated depending on what the causes are, and ovulation can be induced with medication. Up to 50% of women on medication who ovulate will get pregnant within three months.
