I have irregular periods and long cycles, yet my blood test results are good, where does this problem come from?

Having long and irregular menstrual cycles can potentially impact fertility in some cases, but it varies from woman to woman. The key is to understand your ovulation pattern within the cycle. If you consistently ovulate each cycle, even with a longer cycle, fertility should not be a major concern. However, if your body skips ovulations, it would be advisable to consult with a healthcare provider for further evaluation and guidance.
