What is the likelihood of getting pregnant this way?


Doctor, I would like to ask about my irregular menstruation.
My period in March was from March 30 to April 4, and in April, my period started on April 10.
It lasted until the 13th or 14th, with some brown discharge for a couple of days.
The cycles are very close together, and then on the 14th, I had unprotected intercourse.
I took a pregnancy test on the 20th, and it showed one line, indicating negative.
Is it accurate to test this early?

Xiao Jun, 30~39 year old female. Ask Date: 2016/04/20

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, a pregnancy test should be taken at least 12 days after conception for accurate results.
If you suspect pregnancy, it's best to use preventive measures beforehand.
If your period is more than a week late, it is advisable to consult a gynecologist.
Wishing you good health.

When it comes to understanding pregnancy chances with irregular menstrual cycles, it's important to recognize that irregular cycles can complicate the timing of ovulation, which is crucial for conception. In a typical menstrual cycle, ovulation occurs about 14 days before the start of the next period. However, with irregular cycles, predicting ovulation can be challenging, leading to uncertainty about the chances of becoming pregnant.

In your case, you mentioned that your menstrual cycle has been inconsistent, with periods occurring on March 30 to April 4 and then again on April 10. This irregularity can make it difficult to determine when you ovulated. If you had unprotected intercourse on April 14, it's essential to consider that sperm can survive in the female reproductive tract for up to five days. Therefore, if you ovulated shortly after your last period, there is a possibility of conception.

Regarding the pregnancy test you took on April 20, it is generally recommended to wait until at least the first day of your missed period for the most accurate results. Testing too early can lead to a false negative result, especially if your body has not yet produced enough human chorionic gonadotropin (hCG), the hormone detected by pregnancy tests. Since your period was expected around April 10, testing on April 20 might still be considered early, particularly if your cycles are irregular.

If you are concerned about your menstrual irregularity and its impact on your ability to conceive, it may be beneficial to consult with a healthcare provider. They can help assess your menstrual cycle, evaluate any underlying conditions that may be affecting your cycle regularity, and provide guidance on optimizing your chances of conception.

In addition, keeping track of your menstrual cycle, noting any changes, and using ovulation predictor kits can help you better understand your ovulation patterns. This information can be valuable when trying to conceive, as it allows you to identify your fertile window more accurately.

In summary, while irregular menstrual cycles can complicate the process of conception, it is still possible to become pregnant. If you suspect you might be pregnant, consider retesting a few days later or consulting with a healthcare professional for further evaluation and guidance.
