Missed menstruation?

Hello, my last menstrual period started on July 12 and ended on July 18.
My cycles have been quite regular, around 31 days, and I have been keeping track.
Normally, I would expect my period to start between the 12th and 15th of this month, but today is already the 18th and it hasn't arrived yet.
I had sexual intercourse on August 14, but we used protection throughout.
Should I wait a few more days or go for a check-up right away?

Hello Miss Xiao Wang: If your menstrual cycle has been regular, then the chances of conception from sexual intercourse on August 14th are low, especially since you used condoms throughout.
There's no need to worry too much.
However, since probabilities can be uncertain, if you're concerned, it's best to take a pregnancy test to get a definitive answer.
If you prefer to wait a few days to see, that's also fine.

More Info

When it comes to missed periods, especially for someone with a previously regular cycle, it can be concerning and confusing. Given your situation, where your last menstrual period started on July 12 and ended on July 18, and considering your cycle typically lasts about 31 days, your next period would be expected around August 12 to August 15. Since today is August 18 and your period has not arrived, it is understandable that you are feeling anxious.

First, it's important to consider a few factors that could contribute to a missed period. Stress, changes in weight, exercise habits, and even illness can impact your menstrual cycle. Additionally, hormonal fluctuations can occur naturally, which might cause a delay. Since you mentioned that you had sexual intercourse on August 14 but used protection, the likelihood of pregnancy is significantly reduced, but not entirely eliminated. Condoms are generally effective, but they can occasionally fail due to breakage or slippage.

In terms of what to do next, it is generally recommended to wait a few days to see if your period arrives. Many women experience occasional delays in their cycles, and it might just be a temporary issue. However, if your period does not arrive within a week or so, it would be wise to take a home pregnancy test. These tests are widely available, easy to use, and can provide results within minutes. If the test is negative and your period still does not come, or if you experience other concerning symptoms such as severe pain, unusual discharge, or other health issues, it would be advisable to seek medical advice.

If you do decide to visit a healthcare provider, they may conduct a physical examination, review your medical history, and possibly perform blood tests or ultrasounds to determine the cause of your missed period. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances can also lead to irregularities in your menstrual cycle.

In summary, while it is reasonable to wait a few more days to see if your period arrives, if it does not, taking a home pregnancy test is a good next step. If the test is negative and your period remains absent, or if you have any other health concerns, seeking medical advice would be the best course of action. Remember, your health and peace of mind are important, and it’s always better to err on the side of caution when it comes to your reproductive health.
