More Info


To address your question about the possibility of getting pregnant two days before your period, it's important to understand the menstrual cycle and the timing of ovulation. The menstrual cycle typically lasts between 21 to 35 days, with an average of about 28 days. Ovulation usually occurs around 14 days before the start of your next period. Therefore, if your cycle is regular and you have a 28-day cycle, ovulation would typically occur around day 14, with your next period starting around day 28.

In your case, if your last menstrual period started on April 17, and you had unprotected intercourse on May 15, this timing is crucial. If we assume a standard 28-day cycle, your next period would be expected around May 15. If you had intercourse just before your expected period, it is less likely that you would conceive, as ovulation would have already occurred about two weeks prior. Sperm can survive in the female reproductive tract for up to five days, so if you had unprotected sex just before your period, the chances of pregnancy are low, especially if you are close to the start of your menstrual cycle.

Regarding your pregnancy test showing a single line, this typically indicates a negative result, meaning that you are not pregnant. However, it's essential to consider that home pregnancy tests are most accurate when taken after a missed period. If you test too early, the hormone hCG (human chorionic gonadotropin), which is produced during pregnancy, may not be at detectable levels yet. If your period does not arrive as expected, it may be a good idea to retest a few days later or consult with a healthcare provider for further evaluation.

In summary, based on the timing of your sexual activity relative to your menstrual cycle, it is unlikely that you would conceive from intercourse two days before your expected period. The negative pregnancy test further supports this conclusion. However, if you continue to have concerns about your menstrual cycle or potential pregnancy, it is advisable to seek guidance from a healthcare professional who can provide personalized advice and support.
