Menstruation is delayed?


Hello, I would like to ask about my menstrual cycle.
I estimated that my period would start on September 8, but I'm not sure if drinking too many cold beverages has caused a delay.
Additionally, on September 16, I only had external contact with my boyfriend without penetration or ejaculation, but I took emergency contraception on September 17.
I have taken two pregnancy tests, both showing one line.
Is there a chance of pregnancy? Could this cause a delay in my period? When can I expect my menstruation to arrive?

zero zero, 10~19 year old female. Ask Date: 2022/09/24

Hello, the effects of emergency contraceptive pills on menstruation can vary; they may cause your period to come early or late.
Additionally, their contraceptive effectiveness is not 100%, with a failure rate of about 3%.
If your period still hasn't arrived, it is advisable to consult a gynecologist to check for hormonal imbalances or other reasons.
Thank you! Wishing you peace and health.
Dr.

Delayed menstruation can be a source of concern for many individuals, and understanding the potential causes is essential for addressing any worries you may have. In your case, several factors could contribute to the delay in your menstrual cycle.

Firstly, it’s important to note that menstrual cycles can be influenced by a variety of factors, including stress, hormonal imbalances, changes in weight, and lifestyle choices, such as diet and exercise. Consuming excessive cold beverages, like ice drinks, is unlikely to have a direct impact on your menstrual cycle. However, if this change in diet is part of a broader shift in your eating habits or if it coincides with other stressors, it could potentially contribute to a delay.

Regarding your sexual activity, it's crucial to understand that while the risk of pregnancy from external genital contact (such as friction without penetration) is generally low, it is not entirely absent. The presence of pre-ejaculatory fluid can carry sperm, which may lead to pregnancy if it comes into contact with the vaginal area. However, since you took emergency contraception (the "morning-after pill") on September 17, this significantly reduces the likelihood of pregnancy, especially if taken within the recommended timeframe after unprotected intercourse.

The negative pregnancy tests you conducted further support the low likelihood of pregnancy. Home pregnancy tests are typically reliable when used correctly, especially if taken after a missed period. If you tested negative and your period is still delayed, it is likely due to other factors rather than pregnancy.

As for when your period might arrive, it can be difficult to predict. The hormonal changes induced by stress, emergency contraception, or other lifestyle factors can lead to variations in the menstrual cycle. It’s not uncommon for periods to be delayed for a few days to a couple of weeks after taking emergency contraception, as it can temporarily disrupt your normal hormonal balance.

If your period does not arrive within a week or two, it would be advisable to consult a healthcare professional for further evaluation. They can assess your situation more comprehensively, considering factors such as your medical history, any additional symptoms you may be experiencing, and the results of your pregnancy tests. They may also recommend further testing or examinations to rule out other potential causes of delayed menstruation, such as hormonal imbalances or underlying health conditions.

In summary, while your concerns about delayed menstruation are valid, the combination of factors you described—such as the use of emergency contraception and the nature of your sexual activity—suggests that pregnancy is unlikely to be the cause. However, if your period does not return soon, seeking medical advice would be the best course of action to ensure your reproductive health is monitored and managed appropriately.
