What Is A Normal Period?

  • Irregular periods: Cycles outside of the normal range, missed cycles, or prolonged cycles are considered abnormal.
  • Menorrhagia: Large amounts of blood loss during periods (80ml per cycle or more) or lasting longer than seven days.
  • Anovulatory cycles: Periods that occur without ovulation. Most commonly due to hormone imbalance or gynecologic immaturity.
  • Dysmenorrhea: Pain with periods.
  • Polycystic Ovary Syndrome: A common cause of irregular periods in which the body makes too much testosterone. It can cause increased body hair, acne, weight gain and glucose intolerance.

Frequently Asked Questions

What happens if I miss a dose of the oral contraceptive pill?

ANSWER: If you miss one pill, take it as soon as you remember. If you miss more than one pill, please follow the instructions that came with your contraceptive pills.

If I take hormones, will I still be able to get pregnant later in life?

ANSWER: Yes, all of these hormones are completely reversible, and their effects wear off within a few days to a few months after you stop using them.

What if I don’t like the treatment option I chose?

ANSWER: It may take you a few months to adjust to many of these treatment options, but you can change your mind if you do not like the method you chose and try something that may work better for you.

These have a lot of side effects! Will I have all of these?

ANSWER: Every person responds to hormones differently, and it’s impossible to know what side effects, if any, you’ll experience until you start the treatment.

Do my parents need to know I’m getting treated?

ANSWER: We encourage you to talk openly with your parent/guardian about your concerns and questions; however, you can receive confidential treatment for birth control, sexually transmitted infections or drug use.

How do I choose the right method?

ANSWER: There is no one-size-fits-all approach to choosing hormones. Talk with your doctor about your goals for starting treatment to help you decide.

Can I stop using these at any time?

ANSWER: Yes. Please ask your doctor about the best way to stop your specific treatment.
