Menstrual cycle-related sexual activity
If your menstrual period started on October 16 and ended on October 21, and you had unprotected intercourse with ejaculation on October 22 and 23, the likelihood of pregnancy can be relatively high.
This is because sperm can survive in the female reproductive tract for several days, and ovulation typically occurs around 12 to 16 days after the start of your last period.
If you have a regular cycle, you may be close to your fertile window.
If you are concerned about the possibility of pregnancy, consider taking a home pregnancy test if your next period is late, or consult with a healthcare provider for further advice.

Hello, the chances of pregnancy are low, but it is always best to take preventive measures beforehand.
Do not rely on the safe period.
If your period is more than a week late, it is advisable to see a gynecologist.
Wishing you good health.

More Info
When considering the risk of pregnancy after unprotected sex, it is essential to understand the timing of the menstrual cycle, ovulation, and the nature of the sexual activity. Based on your provided dates, you had your menstrual period from October 16 to October 21, and then you engaged in unprotected sex on October 22 and 23.
The menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation usually occurs around 14 days before the next expected period. In your case, if your cycle is regular and lasts about 28 days, ovulation would likely occur around day 14 of your cycle, which would be approximately October 30. However, if your cycle is longer, say 30 to 35 days, ovulation could occur later, around November 1 to November 5.
Since you had unprotected sex just one or two days after your period ended, the likelihood of becoming pregnant is relatively low, but not impossible. Sperm can live inside the female reproductive tract for up to five days, so if you were to ovulate shortly after your sexual activity, there is a chance that sperm could fertilize an egg. However, given the timing, it is less likely that you would conceive from intercourse on October 22 or 23.
If you are concerned about the possibility of pregnancy, it is advisable to monitor your body for any signs of pregnancy, such as missed periods, breast tenderness, nausea, or unusual fatigue. If your next period is late by a week or more, taking a home pregnancy test would be a good idea. These tests are generally reliable and can provide you with a clear answer.
In addition, if you are sexually active and not planning for pregnancy, consider discussing contraceptive options with a healthcare provider. There are various methods available, including hormonal birth control, intrauterine devices (IUDs), and barrier methods, which can help prevent unintended pregnancies in the future.
If you experience any unusual symptoms, such as severe abdominal pain or heavy bleeding, it is important to seek medical attention promptly, as these could indicate other health issues that require evaluation.
In summary, while the risk of pregnancy from unprotected sex immediately after your period is relatively low, it is not zero. Monitoring your cycle and being aware of your body’s signals will help you manage your reproductive health effectively. If you have further concerns or questions, consulting with a healthcare professional is always a wise choice.
