When it comes to understanding the chances of pregnancy from non-penetrative sexual activities, it's essential to clarify a few key points regarding how pregnancy occurs and the factors that influence it.
1. Understanding Pregnancy Mechanisms: Pregnancy typically occurs when sperm fertilizes an egg. This usually happens through vaginal intercourse, where sperm is deposited in the vagina and can travel through the cervix into the uterus to meet an egg. However, pregnancy can also occur through other means if sperm comes into contact with the vaginal area, even without penetration.

2. Non-Penetrative Activities: In your scenario, you mentioned engaging in activities such as oral sex and manual stimulation. If your fingers, which had previously touched your penis, then came into contact with the vaginal area, there is a potential risk for pregnancy. Sperm can survive on skin and may be transferred in this manner. However, the likelihood of pregnancy from such activities is significantly lower compared to direct vaginal intercourse.

3. Specific Situations:
- In the first situation you described, where there was no penetration but your fingers touched the vaginal area after being on your penis, the risk of pregnancy exists but is relatively low. The sperm would need to be viable and in sufficient quantity to lead to fertilization, which is less likely in this scenario.

- In the second situation, where there was contact but no penetration, the risk remains similar. If there was no ejaculation near the vaginal opening, the chances of pregnancy are minimal. However, if there was any pre-ejaculate fluid (which can contain sperm), there is still a slight risk.

4. Timing and Ovulation: The timing of your partner's menstrual cycle is also crucial. If her last period started around January 18-19, and you had sexual contact on January 30, she would likely be nearing her ovulation period (which typically occurs about 14 days after the start of her last period). This is when she is most fertile, and thus the risk of pregnancy is higher if sperm were to come into contact with her vaginal area.

5. Conclusion: While the chances of pregnancy from the activities you described are low, they are not zero. If your partner is concerned about the possibility of pregnancy, it would be wise for her to take a pregnancy test if her period is late. Additionally, if you are looking to prevent pregnancy in the future, consider discussing contraceptive options with a healthcare provider.
6. Health Considerations: It's also important to note that engaging in sexual activities, even non-penetrative ones, should always be consensual and safe. Practicing good hygiene and understanding the risks involved can help ensure both partners feel comfortable and secure in their sexual experiences.

In summary, while the risk of pregnancy from non-penetrative sexual activities is lower than from penetrative intercourse, it is not entirely absent. Awareness of the menstrual cycle, the nature of the sexual activities, and the presence of sperm are all critical factors in assessing pregnancy risk. If there are any concerns, consulting with a healthcare professional can provide personalized advice and guidance.
