Is it possible to become pregnant?

Hello, doctor.
My girlfriend's menstrual cycle has been very irregular.
Her last period was on December 27, and she hasn't had one since.
The last sexual intercourse was on February 1, during which we used a condom and confirmed it did not break.
Recently, on February 5 and 6, she started experiencing increased vaginal discharge, which has been enough to wet her underwear.
She feels lightheaded and nauseous but hasn't vomited.
Her appetite and mood are normal, and she occasionally has diarrhea.
Could this be premenstrual syndrome, or is there a possibility of pregnancy?

Hello Mr.
Shi: Your girlfriend has irregular menstrual cycles, so I recommend that you use condoms during all sexual intercourse before considering other contraceptive methods, such as taking birth control pills.
Since her period is already 10 days late and she is experiencing nausea, we cannot rule out the possibility of pregnancy.
It is advisable for her to take a urine test to check for pregnancy, as this would be more prudent.

When considering the possibility of pregnancy, especially in the context of irregular menstrual cycles, it's important to understand the various symptoms and signs that can indicate either premenstrual syndrome (PMS) or early pregnancy. In your case, your girlfriend has experienced irregular periods, with her last menstrual cycle starting on December 27 and no menstruation since then. The recent sexual encounter on February 1, which was protected, adds another layer to this situation.

Firstly, it's essential to recognize that irregular menstrual cycles can be caused by a variety of factors, including stress, hormonal imbalances, changes in weight, and underlying health conditions. These irregularities can sometimes make it challenging to determine whether a missed period is due to pregnancy or other factors.
The symptoms your girlfriend is experiencing—excessive discharge, dizziness, nausea (though she hasn't vomited), normal appetite, and occasional diarrhea—can be indicative of several conditions. In early pregnancy, women may experience increased vaginal discharge due to hormonal changes, as well as nausea and dizziness. However, these symptoms can also align with PMS, especially if she is experiencing hormonal fluctuations leading up to her expected period.

To clarify the situation regarding the possibility of pregnancy, it is important to consider the timing of ovulation and the menstrual cycle. If your girlfriend has irregular cycles, predicting ovulation can be difficult. Typically, ovulation occurs about 14 days before the start of the next period. If her cycle is longer or shorter than the average 28 days, this can shift the timing of ovulation. If she ovulated later than usual, it is possible that the symptoms she is experiencing could be related to early pregnancy.

Given that she had unprotected sexual intercourse on February 1, and considering the timing of her last period, it would be prudent to take a home pregnancy test if her period does not arrive soon. Home pregnancy tests are generally reliable and can detect pregnancy hormones in urine about a week after a missed period.
Additionally, if she continues to experience symptoms such as dizziness and nausea, or if there are any concerns about her health, it would be wise for her to consult with a healthcare provider. A medical professional can conduct a blood test for pregnancy, which is more sensitive than a urine test, and can also evaluate her symptoms in the context of her overall health.

In summary, while the symptoms your girlfriend is experiencing could suggest either PMS or early pregnancy, the irregularity of her menstrual cycle complicates the situation. A home pregnancy test would be a logical next step, and if there are any concerning symptoms or if she wishes to discuss her irregular cycles further, a visit to a healthcare provider is recommended. This will help ensure that she receives appropriate care and guidance based on her individual health needs.
