When it comes to the question of whether you can get pregnant after unprotected intercourse, it's essential to understand the mechanics of conception and the associated risks. In your scenario, where there was a combination of pre-ejaculate (pre-cum) and subsequent intercourse with and without a condom, there are several factors to consider.

Firstly, it's important to note that pre-ejaculate fluid can contain sperm. While the concentration of sperm in pre-ejaculate is generally lower than in ejaculate, it is still possible for pregnancy to occur if sperm is present. If the male partner had recently ejaculated and then engaged in sexual activity again without a condom, there is a risk of sperm being present in the pre-ejaculate fluid. Therefore, even if there was a delay between ejaculation and penetration, the risk of pregnancy is not negligible.

Regarding the timing of your pregnancy test, it is crucial to understand the window for accurate testing. Most home pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin) in urine, which is produced shortly after a fertilized egg implants in the uterus. This typically occurs about 6 to 10 days after conception. For the most reliable results, it is recommended to wait until at least the first day of your missed period, which is usually about two weeks after ovulation. If you took a pregnancy test two weeks after the intercourse and it showed only one line (negative), it is likely that you are not pregnant, but it is still advisable to retest a few days later or consult a healthcare provider for a blood test if you have concerns.

In summary, while there is a risk of pregnancy from the scenario you described, the likelihood depends on several factors, including the presence of sperm in pre-ejaculate and the timing of ovulation. If you are concerned about potential pregnancy or sexually transmitted infections (STIs), it is always a good idea to consult with a healthcare provider for personalized advice and possible testing. Additionally, discussing contraception options with a healthcare professional can help prevent unintended pregnancies in the future.
