Hello, based on your description, there is a possibility of pregnancy.
However, there are currently no statistical figures available for the points 1 and 5 you mentioned, as they are not typical behaviors and cannot be investigated.
Pregnancy tests are usually more accurate after two weeks of conception.
It is not possible to determine pregnancy based solely on subjective symptoms.
I recommend that if your period is more than a week late, you should take a urine test to check for pregnancy.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info

When it comes to the question of whether oral sex can lead to pregnancy, it’s essential to understand the mechanics of conception and the risks involved. Based on the scenario you've described, let’s break down the concerns and clarify the facts.

1. Pregnancy Risk from Oral Sex: In your situation, the primary concern is whether sperm can travel from your girlfriend's mouth to her vagina and lead to pregnancy. While it is theoretically possible for sperm to be transferred in this manner, the likelihood is extremely low. Sperm needs a conducive environment to survive and swim effectively, and the oral cavity is not ideal for this. Additionally, if your girlfriend swallowed most of the semen and only a small amount was transferred, the chances of pregnancy remain minimal.
2. Menstrual Irregularities: If your girlfriend is experiencing irregular periods, it could be due to various factors, including stress, hormonal changes, or potential pregnancy. If there is a concern about pregnancy, it’s advisable to take a pregnancy test.

3. Timing for Pregnancy Tests: Home pregnancy tests are most accurate when taken after a missed period, which is typically about one to two weeks after conception. This is because it takes time for the hormone hCG (human chorionic gonadotropin) to build up in the body to detectable levels.

4. Physical Symptoms: Changes in the breasts, such as darkening of the areola and tenderness, can be early signs of pregnancy. However, these symptoms can also be associated with premenstrual syndrome (PMS). If your girlfriend is experiencing these changes along with a missed period, it would be wise to take a pregnancy test.

5. Impact of Saliva on Sperm: Saliva can affect sperm motility and viability. While it is not a significant factor in the context of your scenario, it is generally advised to avoid using saliva as a lubricant during sexual activities, as it can alter the pH balance and potentially harm sperm.

In summary, while the scenario you described involves several factors that could theoretically lead to pregnancy, the actual risk remains low. If there are concerns about pregnancy or menstrual irregularities, the best course of action is to take a pregnancy test and consult with a healthcare provider for personalized advice. It’s also important to communicate openly with your partner about sexual health and any concerns that arise.
