Pregnancy test questions?
Hello doctor, my last menstrual period was from September 21 to September 26.
I had unprotected intercourse with my boyfriend on September 25, but he did not ejaculate.
I asked him to pull out quickly, and I took emergency contraception within two hours after the encounter.
On October 1, I experienced bleeding that was about the same amount as the third day of a normal period, lasting for four days, which seemed quite normal.
My cycle is approximately 27 days, and my app indicated a fertile window from September 29 to October 5.
Yesterday, I visited a gynecologist for a pregnancy test.
I had urinated once and had some drinks before the test, and the result showed one line.
Can I confirm that I am not pregnant? It has been 25 days since the sexual encounter; is this result accurate?

More Info
Hello! Thank you for your question regarding pregnancy tests and the concerns surrounding them. Based on the information you've provided, it seems you have taken several steps to prevent pregnancy and have also undergone a pregnancy test. Let's break down your situation and clarify the accuracy of your test results.
First, you mentioned that you had unprotected intercourse on September 25 and took emergency contraception (the morning-after pill) within two hours. This is a crucial step in preventing pregnancy after unprotected intercourse. Emergency contraception is most effective when taken as soon as possible after the incident, and it can significantly reduce the risk of pregnancy if taken within 72 hours.
You experienced bleeding starting on October 1, which lasted for four days and was similar to your normal menstrual flow. This bleeding could be a side effect of the emergency contraception, as these medications can cause changes in your menstrual cycle, including earlier or lighter periods. The timing of your bleeding, occurring just a few days after taking the emergency contraceptive, suggests that it may have been effective in preventing pregnancy.
You also mentioned that you took a pregnancy test after this bleeding and received a negative result (one line). Pregnancy tests are generally very accurate when used correctly, especially when taken after a missed period. Since you had your bleeding and the test was taken 25 days after the unprotected intercourse, it is reasonable to conclude that the test result is accurate and that you are likely not pregnant.
However, it is important to note that while home pregnancy tests are reliable, they can occasionally yield false negatives, especially if taken too early or if the urine is diluted (for example, if you drank a lot of fluids before testing). If you still have concerns or if your next period is late, it may be a good idea to take another test or consult with your healthcare provider for further evaluation.
In summary, based on your timeline and the actions you've taken, it appears that you are not pregnant. The emergency contraception you took, along with the subsequent bleeding and negative pregnancy test, supports this conclusion. However, if you have any lingering doubts or experience any unusual symptoms, don't hesitate to reach out to your healthcare provider for personalized advice and reassurance.
It's also worth mentioning that understanding your menstrual cycle and the timing of ovulation can help in managing your reproductive health. If you have further questions about contraception or pregnancy, feel free to ask!
