Delayed Menstruation: Causes and Pregnancy Concerns

Missed menstruation?

Hello, doctor.
My last menstrual period started on April 22, but I have been experiencing hormonal imbalances in the past few months and took medication to regulate my cycle.
The obstetrician-gynecologist mentioned that I should gradually adjust my endometrium, and my usual cycle is about 32 days.
This time, it has already exceeded that cycle, and my period has not arrived yet.
On May 16, my partner touched my genital area, but I am not sure if there was any contact with pre-ejaculate fluid or sperm, as he did not penetrate my vagina and there was a layer of clothing in between.

1.
What is the likelihood of pregnancy in this situation?
2.
What could be the possible reasons for the absence of menstruation?

Hello, it is unlikely that you are pregnant; it may still be a hormonal imbalance.
Wait for another week, and if your period still does not arrive, it is advisable to see a gynecologist.
Wishing you good health.

More Info

Understanding delayed menstruation can be a complex issue, especially when considering the potential for pregnancy and the various factors that can influence menstrual cycles. In your case, you mentioned that your last menstrual period was on April 22, and you typically have a cycle of about 32 days. Given that you are now past this cycle without menstruation, it is understandable to have concerns.

1. Pregnancy Risk: Based on your description, the risk of pregnancy from the situation you described (manual stimulation without penetration) is generally considered low. Sperm needs to be deposited in the vaginal canal for pregnancy to occur, and while pre-ejaculate fluid (pre-cum) can contain sperm, the likelihood of pregnancy from indirect contact through clothing is minimal. However, it is not impossible, especially if there was any direct contact with seminal fluid. If you are concerned about the possibility of pregnancy, taking a home pregnancy test can provide clarity. These tests are most accurate when taken after a missed period.

2. Causes of Delayed Menstruation: There are several reasons why your period may be delayed, especially considering your history of hormonal imbalance. Some common causes include:
- Hormonal Imbalance: Since you have previously experienced endocrine issues, it is possible that your body is still adjusting. Hormonal fluctuations can lead to irregular cycles and missed periods.

- Stress: Emotional or physical stress can significantly impact your menstrual cycle. Stress can affect the hypothalamus, which regulates hormones that control menstruation.

- Weight Changes: Significant weight loss or gain can also disrupt your menstrual cycle. Body fat plays a role in hormone production, and changes can lead to irregularities.

- Medical Conditions: Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other underlying health issues can cause delayed menstruation.

- Medications: If you have been taking medications to regulate your cycle, these can also affect the timing of your menstruation.

Given these possibilities, it is advisable to consult with your healthcare provider. They can perform a thorough evaluation, which may include a physical examination, blood tests to check hormone levels, and possibly an ultrasound to assess your reproductive organs. This will help determine the underlying cause of your delayed menstruation and guide appropriate management.

In the meantime, if you are experiencing any unusual symptoms such as severe pain, heavy bleeding, or other concerning signs, seek medical attention promptly. It is essential to prioritize your health and well-being during this time. Remember, open communication with your healthcare provider is crucial for addressing your concerns and ensuring you receive the best care possible.
