Understanding male ejaculation and the associated risks of pregnancy during ovulation is a complex topic that involves several physiological and biological factors. Let's break down the concerns raised in your question.


Male Ejaculation and Sperm Presence
When a male becomes sexually aroused, he may produce pre-ejaculatory fluid, commonly referred to as "pre-cum." This fluid is secreted by the Cowper's glands and serves several purposes, including lubricating the urethra and neutralizing any acidity that may be present from urine. Importantly, while pre-ejaculatory fluid itself typically contains very few sperm, it is possible for sperm to be present, especially if there has been a recent ejaculation. This means that even if ejaculation does not occur, there is still a risk of pregnancy if sperm are present in the pre-ejaculatory fluid.


Risks of Pregnancy During Ovulation
The timing of sexual intercourse in relation to a woman's ovulation cycle is critical when considering the risk of pregnancy. Ovulation typically occurs around the midpoint of a woman's menstrual cycle, and this is when an egg is released from the ovary and is available for fertilization. If sexual activity occurs during this fertile window, the chances of conception are significantly higher.

If you are engaging in sexual activity during the ovulation period, even with limited penetration or without full ejaculation, there is still a potential risk of pregnancy due to the presence of sperm in pre-ejaculatory fluid. Therefore, it is essential to consider that any sexual activity during this time could lead to pregnancy.


Presence of Blood and Other Discharges
The mention of "少量血絲" (a small amount of blood) in the discharge could be concerning and may warrant further investigation. This could be due to various reasons, including irritation or minor trauma to the vaginal or cervical tissues, especially if there was any friction during sexual activity. It is advisable to consult a healthcare professional if this symptom persists or is accompanied by other unusual signs.


Emergency Contraception and Pregnancy Testing
Regarding the need for emergency contraception (often referred to as the "morning-after pill"), it is typically recommended if there is a concern about potential pregnancy following unprotected intercourse or contraceptive failure. If your healthcare provider has indicated that there is no need for emergency contraception, it may be because they assessed the risk of pregnancy to be low based on the specifics of your situation.

As for pregnancy testing, if there is a concern about potential pregnancy, it is advisable to wait until after the expected date of menstruation to take a home pregnancy test for the most accurate results. If menstruation does not occur, a pregnancy test can confirm whether or not conception has taken place.


Conclusion
In summary, while the risk of pregnancy may be lower with limited penetration and the use of pre-ejaculatory fluid, it is not entirely absent, especially during the ovulation period. If there are any concerns about potential pregnancy or unusual symptoms, it is always best to consult with a healthcare provider for personalized advice and guidance. They can provide clarity on the risks involved and help address any symptoms or concerns you may have.
