Hello, you are unlikely to be pregnant.
If your period still hasn't arrived after a week, it is advisable to see a gynecologist.
Wishing you good health.

More Info

When it comes to missed periods and pregnancy concerns, especially for first-time experiences, there are several factors to consider. Based on your timeline, you had your last menstrual period on July 17, and after having sexual intercourse on August 13 with protection, you took pregnancy tests on August 30 and September 2, both of which returned negative results. Now, you are experiencing a missed period.

1. Possibility of Pregnancy: Given that you used a condom and also practiced withdrawal, the likelihood of pregnancy is relatively low. However, no contraceptive method is 100% effective. The negative pregnancy tests you took are also indicative that you are likely not pregnant, especially if they were taken after a missed period. Pregnancy tests are most accurate when taken after a missed period, so if you have not had your period yet, it might be worth waiting a few more days and testing again, or consulting with a healthcare provider for a blood test, which can detect pregnancy earlier than urine tests.

2. Menstrual Cycle Variability: It is common for first-time sexual experiences to cause anxiety or stress, which can affect your menstrual cycle. Stress can lead to hormonal fluctuations that might delay ovulation or menstruation. Additionally, changes in routine, diet, or physical activity can also impact your cycle. If this is your first time having sexual intercourse, it is possible that the experience, coupled with any anxiety or excitement surrounding it, could contribute to a delayed period.

3. Other Factors: Other factors that could contribute to a missed period include weight changes, illness, excessive exercise, or hormonal imbalances. If you have recently experienced any significant changes in your lifestyle or health, these could also be influencing your menstrual cycle.

4. When to Seek Medical Advice: If your period does not arrive within a week or two, or if you continue to experience symptoms such as nausea, breast tenderness, or fatigue, it would be advisable to consult with a healthcare provider. They can provide further evaluation and guidance, including potential tests to rule out pregnancy or other underlying conditions.

In summary, while the chances of pregnancy seem low given the precautions taken, it is important to monitor your body and consider other factors that might be affecting your menstrual cycle. If you have concerns or if your period does not return, seeking medical advice is always a good step to ensure your health and peace of mind.
