Can Pre-Ejaculate Fluid Cause Pregnancy? Menstrual Delays

Menstrual issues

Hello, Doctor.
I have a question.
If I perform oral sex on my boyfriend (but he ejaculates outside), and although I ingest some pre-ejaculate fluid but then spit it out, is there a chance of becoming pregnant? Can my boyfriend's pre-ejaculate fluid cause pregnancy? Also, my period is a week late, so I wanted to ask.
Thank you.

More Info

Pre-ejaculate fluid, often referred to as pre-cum, is a clear fluid that is released from the penis before ejaculation. It is produced by the Cowper's glands and serves several purposes, including lubricating the urethra and neutralizing acidity. One of the common concerns regarding pre-ejaculate fluid is whether it can cause pregnancy.

To address your question, yes, there is a possibility, albeit a small one, that pre-ejaculate fluid can lead to pregnancy. This is primarily because pre-ejaculate can sometimes contain sperm. If a male has recently ejaculated and there are still sperm present in the urethra, some of these sperm can be carried out with the pre-ejaculate fluid. Therefore, if pre-ejaculate fluid comes into contact with the vaginal canal, there is a risk of sperm reaching the egg and resulting in pregnancy.

In your case, since you mentioned that your boyfriend did not ejaculate inside you and that you expelled the pre-ejaculate fluid after oral sex, the risk of pregnancy is significantly reduced. However, it is important to note that while the likelihood is low, it is not zero. If you are experiencing a delay in your menstrual cycle, it may be a good idea to take a pregnancy test to confirm whether or not you are pregnant. Menstrual delays can occur for various reasons, including stress, hormonal imbalances, changes in weight, or other health issues, so it is essential to consider these factors as well.

If you are actively trying to avoid pregnancy, it is advisable to use reliable contraception methods. Condoms, hormonal birth control, or other forms of contraception can help prevent unintended pregnancies and also protect against sexually transmitted infections (STIs).

In summary, while pre-ejaculate fluid can potentially lead to pregnancy, the risk is relatively low if there was no ejaculation inside the vagina. If your menstrual cycle is delayed, consider taking a pregnancy test and consult with a healthcare provider for further guidance. They can help you understand your menstrual cycle better and discuss appropriate contraceptive options if you're looking to prevent pregnancy in the future.
