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

To determine whether you can get pregnant based on your provided timeline, we need to consider a few key factors: your menstrual cycle, ovulation timing, and the lifespan of sperm and eggs.

1. Understanding Your Menstrual Cycle: You mentioned that your last menstrual period (LMP) started on March 18 and ended on March 23. The average menstrual cycle is about 28 days, but it can vary from person to person. If your cycle is regular and approximately 28 days, ovulation typically occurs around 14 days after the first day of your last period. In your case, that would be around April 1.

2. Timing of Intercourse: You had sexual intercourse on March 29 and April 5. If you ovulated around April 1, then the intercourse on March 29 would be well-timed for conception, as sperm can live inside the female reproductive tract for up to five days. Therefore, having intercourse on March 29 could potentially lead to pregnancy if ovulation occurred shortly after.

3. When to Test for Pregnancy: The earliest you can reliably test for pregnancy is usually about one week after your missed period. If your cycle is 28 days, you would expect your next period around April 15. Therefore, you could take a home pregnancy test around April 15 or shortly thereafter for the most accurate result. Testing too early may result in a false negative, as the hormone hCG (human chorionic gonadotropin), which is produced after implantation, may not be detectable yet.

4. Signs of Pregnancy: If you are pregnant, you may start to notice early signs such as missed periods, breast tenderness, nausea, or fatigue. However, these symptoms can also be related to premenstrual syndrome (PMS), so they are not definitive indicators of pregnancy.

5. Fertility Considerations: If you are actively trying to conceive, tracking your ovulation can be very helpful. You can use ovulation predictor kits, monitor basal body temperature, or observe changes in cervical mucus to better understand your fertile window.

In summary, based on your timeline, there is a possibility of getting pregnant from the intercourse on March 29, especially if you ovulated around April 1. You should wait until around April 15 to take a pregnancy test for the most accurate result. If you have further questions or concerns about your fertility or pregnancy, it is always a good idea to consult with a healthcare provider who can provide personalized advice based on your health history and circumstances.
