Can I get pregnant?


Hello doctor, my last menstrual period was from April 23 to April 28.
I had intercourse with my boyfriend on May 6, but there was no ejaculation inside.
I started experiencing a yeast infection on May 14.
My period was supposed to start on May 17, but it hasn't come yet.
Is there a high chance of pregnancy, or could the infection be causing the delay in my period?

More Info


When it comes to the concern of a delayed period and the possibility of pregnancy, there are several factors to consider. Based on your timeline, your last menstrual period (LMP) was from April 23 to April 28, and you had sexual intercourse on May 6. Your expected period was due on May 17, but it has not arrived yet. You also mentioned experiencing a yeast infection starting on May 14.
Firstly, it is important to understand that a missed or delayed period can be caused by various factors, including hormonal imbalances, stress, changes in weight, and infections, such as a yeast infection. In your case, the yeast infection could potentially contribute to the delay in your menstrual cycle. Infections can sometimes disrupt the normal hormonal signals that regulate your menstrual cycle, leading to irregularities.

Regarding the possibility of pregnancy, while you did engage in sexual activity, you mentioned that it was protected with a condom and that there was no ejaculation inside. Condoms are generally effective in preventing pregnancy when used correctly, but they are not 100% foolproof. Factors such as breakage or slippage can occur, which may increase the risk of pregnancy.
To assess your situation more accurately, consider the following steps:
1. Take a Pregnancy Test: The most straightforward way to determine if you are pregnant is to take a home pregnancy test. These tests are designed to detect the hormone hCG (human chorionic gonadotropin), which is produced during pregnancy. It is advisable to wait until at least the first day of your missed period for the most accurate result. However, since you are already a few days late, you can take the test now for a reliable result.

2. Consult a Healthcare Provider: If the pregnancy test is positive, or if you continue to experience symptoms such as delayed menstruation, unusual discharge, or discomfort, it is essential to consult a healthcare provider. They can perform further evaluations, including blood tests or ultrasounds, to confirm pregnancy and assess your overall reproductive health.

3. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as changes in discharge, abdominal pain, or other unusual signs. This information can be helpful for your healthcare provider in diagnosing any underlying issues.

4. Consider Stress and Lifestyle Factors: Sometimes, lifestyle factors such as stress, significant weight changes, or intense physical activity can impact your menstrual cycle. Reflect on any recent changes in your life that may have contributed to your delayed period.

In summary, while there is a possibility of pregnancy given the timing of your sexual activity, the presence of a yeast infection could also be a contributing factor to your delayed period. Taking a pregnancy test and consulting with a healthcare provider will provide you with the clarity you need regarding your situation. Remember, it is always best to seek professional medical advice for personalized guidance and support.
