Understanding the nuances of safe periods and pregnancy risks is crucial for anyone who is sexually active, especially when considering the timing of intercourse in relation to a woman's menstrual cycle. Let's break down your questions regarding the potential for pregnancy and the implications of oral sex.

1. Was the intercourse on November 28 during a safe period? Is there a risk of pregnancy?
To assess whether the intercourse on November 28 was during a safe period, we first need to understand the menstrual cycle. A typical menstrual cycle lasts between 28 to 32 days, with ovulation occurring approximately 14 days before the start of the next period. If your last menstrual period started on November 18 and lasted until November 23, you would likely ovulate around December 2 (assuming a 28-day cycle).
Given this timeline, November 28 falls just a few days before your expected ovulation. This period is considered a "dangerous" or fertile window, where the likelihood of conception is higher. Sperm can survive in the female reproductive tract for up to five days, so if ovulation occurs shortly after intercourse, there is a possibility of pregnancy. Therefore, it is advisable to consider this encounter as potentially risky in terms of pregnancy.

2. Regarding oral sex and the potential for pregnancy:
When it comes to oral sex, the concern about residual sperm leading to pregnancy is generally low. If you performed oral sex and your partner ejaculated in your mouth, the sperm would typically be present in the saliva. Drinking water afterward may help wash away any residual sperm in your mouth, but it does not guarantee complete removal.
However, the primary concern arises when you then touch your mouth and subsequently insert your fingers into the vagina. While the risk of transferring sperm from your mouth to the vagina is theoretically possible, it is considered very low. Sperm needs a specific environment to survive and swim effectively, and the conditions in the mouth and throat are not conducive to this.
That said, if you are concerned about the possibility of pregnancy from this sequence of events, it is essential to remember that the risk remains minimal. The best practice is to maintain good hygiene and avoid touching the vaginal area after oral sex without washing your hands.

Additional Considerations:
If you are worried about the possibility of pregnancy, consider taking a home pregnancy test if your period is late. These tests are generally accurate and can provide peace of mind. If you find yourself frequently concerned about pregnancy risks, it may be beneficial to discuss contraceptive options with a healthcare provider. Various methods, including hormonal birth control, condoms, and intrauterine devices (IUDs), can help prevent unintended pregnancies.

In summary, the intercourse on November 28 was likely within a fertile window, posing a risk for pregnancy. The risk from oral sex is minimal, especially if proper hygiene is maintained. If you have further concerns or experience any unusual symptoms, consulting with a healthcare professional is always a wise choice.
