Pregnancy probability
On December 16, after my period ended, I had intercourse and the condom accidentally broke just as my boyfriend ejaculated.
I took the emergency contraceptive pill, Ella, 40 minutes later.
From December 22 to December 25, I experienced some bleeding, which was slightly less than my usual menstrual flow.
On the evening of December 29, while showering, I noticed brown discharge similar in amount to my usual vaginal discharge, which then stopped.
I used a pregnancy test (from Clearblue) on December 29 and January 3, and both tests showed one line.
Is there still a possibility of pregnancy?

More Info
When it comes to understanding the chances of pregnancy after unprotected intercourse, especially in the context you provided, there are several factors to consider. You mentioned that you had unprotected intercourse on December 16, and the condom broke, followed by taking emergency contraception (Plan B) within 40 minutes. This is a crucial step in preventing pregnancy after unprotected sex.
Emergency contraception is most effective when taken as soon as possible after unprotected intercourse. It can significantly reduce the risk of pregnancy, especially if taken within 72 hours. However, it is important to note that it is not 100% effective. The effectiveness can vary based on where you are in your menstrual cycle at the time of intercourse.
You reported experiencing some bleeding from December 22 to December 25, which could be a side effect of the emergency contraception. Many women experience changes in their menstrual cycle after taking Plan B, including spotting or lighter periods. The brown discharge you observed on December 29 could also be related to hormonal changes caused by the emergency contraceptive.
Regarding your use of pregnancy tests on January 3 and the results showing a single line, this typically indicates a negative result. However, it is important to consider the timing of the test. Pregnancy tests are most accurate when taken after a missed period. Since your menstrual cycle averages 34 days, if your period was expected around January 15, testing before that date may not provide reliable results.
If your period does not arrive by the expected date, it is advisable to take another pregnancy test. If you continue to have negative results but still suspect pregnancy, a visit to a healthcare provider for a blood test can provide more definitive answers, as blood tests can detect lower levels of hCG (the hormone produced during pregnancy) than urine tests.
In summary, while the chances of pregnancy after taking emergency contraception are reduced, they are not eliminated. The bleeding you experienced could be a side effect of the medication rather than a sign of menstruation. If you have concerns or if your period does not come as expected, it is best to consult with a healthcare professional for personalized advice and further evaluation.
