Possible Causes for a Late Period with a Negative Pregnancy Test

If you’ve missed a period and don’t want to be pregnant, you may feel a little frantic. But, what if you’ve missed a period and you have a negative pregnancy test? Even if your negative pregnancy test brings relief, you may still have a lot of questions. Should you take another test? Why is your period still missing? Should you call a doctor? 


Other than pregnancy, a variety of things could cause you to miss your period. So, take a deep breath and let’s talk about some of the possible causes. 


What can cause a missed period? 

Many women miss their periods. One in twenty-five women experience amenorrhea (a missing period for three months or more) in their lifetime. Even though it’s common, you’ll still want to explore possible causes: 


  1. Pregnancy- You’ll first want to rule out pregnancy by taking a test. Most home tests detect a pregnancy around the time a woman misses her period. For free pregnancy testing, make an appointment at Alternatives Medical Clinic
  2. Stress- When you experience any type of stress, your brain may send your body into preservation mode and your period could temporarily stop.
  3. Breastfeeding- If you’re breastfeeding, your period may be irregular. However, be aware that you can still get pregnant again even while breastfeeding.
  4. Medications- Medications such as antidepressants, blood pressure medications, or allergy medications could alter your period. If a doctor recently prescribed these to you, make sure you ask questions about how the medication could affect your period. 
  5. Low Body Weight- Women who experience rapid weight loss or have a low body weight could miss a period. If you’re concerned about your weight, speak to your healthcare provider.
  6. Medical Conditions- Conditions that affect the hypothalamus, pituitary, or thyroid could cause an irregular period.
  7. Gynecological Conditions- Some women who have a history of a cesarean section, a Dilation and curettage (D&C), or surgery for uterine fibroids could develop uterine scar tissue that could cause irregular periods. Also, some women who have Polycystic Ovarian Syndrome (PCOS) experience irregular periods.
  8. Menopause- Around age 50, women’s bodies begin to change as they go through menopause and stop having periods. Early menopause can begin around age 40.
  9. Hormonal Birth Control- Hormonal birth control alters a woman’s cycle, and so sometimes she’ll miss a period. Make sure you talk to your doctor about what to expect. With some birth control, women should continue having a period.
  10. The Morning After Pill– Using emergency contraception could delay your period by a week or two. 


When should I go to the doctor if I’ve missed a period?

Most gynecological doctors recommend seeking medical care if you’ve missed your period for three months or more. They’ll evaluate you for an underlying cause. A doctor may do a pelvic exam, look at the hormone levels in your blood, and obtain a complete medical history. Bring all of your questions and concerns with you to the appointment. 


How do doctors treat a missed period? 

If a woman misses her period, then a doctor will first address the underlying cause. For example, if you miss your period because of stress, you’ll want to decrease the stress in your life. 


Do I need to have a period? 

You need hormones in your body to regulate your menstruation but to also maintain your body. Missing a period indicates that your body doesn’t have the hormonal rhythms it needs to function well. Sometimes prolonged dysregulation could lead to complications such as osteoporosis (weakening of the bones) or cardiovascular disease. So, seek medical care if you’ve missed your period for three months or more. 


Can a sexually transmitted infection cause me to miss my period? 

Typically, a sexually transmitted infection will not cause an irregular period. Some STIs cause bleeding between periods, but most women don’t miss a period. Make an appointment at Alternatives Medical Clinic for free STI testing!


Can I still get pregnant, even if I’ve missed a period? 

In some cases, women who miss a period could still get pregnant because her body may still ovulate. If you’ve missed a period, rule out a pregnancy first. 


What if my period comes back after it was missing? Should I still be worried? 

A woman should be aware of changes in her menstrual cycle. So, it’s always a good idea to keep records of your period- when it starts, how long it goes, and any abnormal symptoms. If your period remains irregular, you should speak with a doctor. 


What do I do if I’ve missed a period, but have a negative pregnancy test? 

Wait a few more days and then take another pregnancy test at home. When used correctly, home tests can detect pregnancy within a few days of a missed period.
