Menstrual Irregularities and Pregnancy Testing: Your Questions Answered

Menstruation, pregnancy test?

Hello doctor, my menstrual period started on January 8 and ended on January 13.
I had sexual intercourse with my boyfriend on January 19, which seemed to be around the time of ovulation (when the chance of pregnancy is higher).
We had unprotected intercourse briefly, but I pulled out before ejaculation, and then we used a condom afterward.
After that, I took a pregnancy test on January 30, which was negative.
According to my menstrual calendar, my next period was expected on February 5, but it did not come, so I took a second test on February 9, which was also negative.
After that, I frequently experienced menstrual cramps, but my period still did not arrive.
I took a third test on February 18 (first thing in the morning), and it was negative.
Tonight, I took a fourth test, and it was still negative.
I would like to ask the doctor if, after so many tests, I can be certain that I am not pregnant? Given that my menstrual cycle has been delayed for so many days, is there still a possibility that my period could come this month? (My menstrual cycle is very irregular; it often alternates between coming one month and not coming the next, so it’s quite unpredictable.)

Hello, the failure rate of using condoms is still around 5%.
It is not possible to determine pregnancy based on subjective symptoms.
There are many factors that can affect the menstrual cycle, so if your period does not arrive as expected, it is advisable to consult a gynecologist for an examination.
Thank you! Wishing you peace and health.

It sounds like you have a lot of concerns regarding your menstrual irregularities and the possibility of pregnancy. Let’s break down your situation and address your questions step by step.

First, based on the timeline you provided, you had your last menstrual period (LMP) on January 8, and you had unprotected intercourse on January 19, which could indeed be around your ovulation period, depending on your cycle length. However, you mentioned that your menstrual cycles are irregular, which can complicate predicting ovulation and the timing of your next period.

You performed multiple pregnancy tests on January 30, February 9, February 18, and again recently, all of which returned negative results. Home pregnancy tests are generally quite reliable, especially when taken after a missed period. The fact that you have tested negative several times suggests that it is unlikely you are pregnant. However, it is important to consider that if your menstrual cycles are irregular, it is possible that your period may be delayed for reasons unrelated to pregnancy.

Irregular menstrual cycles can be caused by a variety of factors, including stress, hormonal imbalances, changes in weight, excessive exercise, or underlying medical conditions such as polycystic ovary syndrome (PCOS). Given that you experience significant irregularity in your cycles, it may be worth consulting with a healthcare provider to explore these potential underlying issues. They can perform a thorough evaluation, which may include blood tests to check hormone levels, and possibly an ultrasound to assess your reproductive organs.

Regarding your concern about whether your period could still arrive this month, it is indeed possible. If your cycles are irregular, it may take longer for your body to regulate itself, and you may experience a delayed period. If you continue to experience menstrual irregularities, it might be beneficial to keep track of your cycles and any other symptoms you experience, as this information can be helpful for your healthcare provider.

If you are experiencing persistent menstrual pain or discomfort, it is also advisable to discuss this with your doctor. They can help determine if there is an underlying issue that needs to be addressed, such as endometriosis or fibroids, which can also contribute to irregular cycles and pain.

In summary, based on the information you provided, it seems unlikely that you are pregnant given the negative tests. However, due to your irregular cycles, it is possible that your period may still arrive later than expected. If your irregularities persist or if you have further concerns, I recommend scheduling an appointment with a healthcare provider for a comprehensive evaluation. They can provide you with personalized advice and treatment options based on your specific situation.
