The most common cause of a missed period is pregnancy. If your period is late and you have been sexually active, call Focus Women’s Center to schedule a free and confidential appointment for pregnancy testing. For more information, check out our Pregnancy Verification and Consultation appointment.
Missed or Irregular Periods
Most biological females who haven’t started menopause will usually have a period every 28 days. For some, it can range between every 21-35 days. During the first year or two of starting your menstrual cycle or later as you near perimenopause or menopause, it can be completely normal to have irregular periods. Additionally, there can be other causes of missed or irregular periods besides pregnancy.
Common Causes for Missed or Irregular Periods Include:
- Emotional stress
- Increased exercise
- Weight loss or weight gain (both low body weight and obesity can cause missed or irregular periods)
- Polycystic Ovarian Syndrome (PCOS)
- Endocrine disorders
- Birth control products such as birth control shots, implants, some IUDs
- Certain medicines
- Diseases such as irritable bowel syndrome, tuberculosis, liver disease, diabetes, etc
If you have missed your period and pregnancy has been ruled out, please consult with your primary healthcare provider.
Please Note: You can still become pregnant even though you are not menstruating regularly or before your first menstrual cycle even starts.
