5 Reasons Your Period May Be Late


Is Your Period Late?

Your period normally comes every 26-29 days, but it is day 30 and your period still isn’t here. You may be wondering why your period hasn’t made its appearance yet. 

Below are some common reasons why your period may be late:

1. Pregnancy

The most common reason your period is late is due to pregnancy. If you are sexually active, even if you are using birth control, you could be pregnant. 

Take a pregnancy test to confirm whether or not you are pregnant. Remember that false negatives are very common, but false positives are not. If you have a positive pregnancy test, you can schedule an appointment with your OBGYN to confirm.

2. Change in birth control 

If you have recently made changes to your birth control then that can be causing the change in your cycle. Many birth control methods lessen the frequency and severity of your period, and some eliminate your period altogether.

Changes to your birth control include a change in your method of contraception, starting birth control for the first time (or for the first time in a while), or stopping your birth control. Talk to your doctor if you have any questions or concerns.

3. Age

As you age, your period will change in length and frequency. A new menstruator will typically have longer and lighter periods, less frequently whereas a menstruator in their 20s or 30s will typically experience heavier and shorter periods more frequently. 

Once you enter your 40’s, your periods may get shorter and lighter or come less frequently. If you are nearing the age of menopause, you could be experiencing perimenopause. Talk to your doctor if you have any questions or concerns.

4. Excess Exercise 

If you have recently started exercising more frequently or more intensely, especially if it is an extreme change from your normal exercise routine, this could lead to your hormones being suppressed. 

This suppression can lead to your period being late or not coming at all. While this may seem like a benefit to your new exercise routine, it can actually be a sign of a more serious health concern.

If you have recently made extreme changes to your exercise or eating habits and now have missed a period, you should reach out to your doctor for a checkup.

5. Hormone Imbalance

A missed or delayed period can also be caused by a hormone imbalance. Many factors can contribute to a hormone imbalance, but some common ones include obesity, increased stress, travel, or extreme changes to your sleep routine. 

If you have any concerns about your health, please make an appointment to talk to your doctor. 


If none of these apply to you, but you still missed a period, talk to your doctor. We always recommend talking to your doctor and advocating for your health! You are worth it.
