Can I get pregnant?


Having unprotected intercourse on the fifth day after your period, without ejaculation, and taking emergency contraception the day after is a common practice.
Experiencing dark brown bleeding starting on the sixth day after taking the emergency contraception can be a normal side effect, as it may indicate hormonal changes or withdrawal bleeding.
However, if the bleeding is unusually heavy, prolonged, or accompanied by severe pain, it is advisable to consult a healthcare professional for further evaluation.

More Info


Post-coital bleeding after taking emergency contraception can be a concerning experience, but it's important to understand the context and possible reasons behind it. In your case, you had unprotected intercourse and took emergency contraception the day after. The bleeding you experienced starting on the sixth day, especially if it is dark brown in color, can be attributed to several factors related to the hormonal changes induced by the emergency contraceptive pill (ECP).

Emergency contraceptive pills, such as those containing levonorgestrel or ulipristal acetate, work primarily by delaying ovulation. They can also cause changes in the uterine lining, which may lead to breakthrough bleeding. This bleeding can occur as a side effect of the hormonal fluctuations that the body experiences after taking the pill. It is not uncommon for women to experience some irregular bleeding or spotting after taking ECPs, and this can manifest as brown discharge, which is often older blood that is taking longer to exit the body.

In general, the timing of your bleeding is consistent with the side effects of emergency contraception. It is typically expected that any bleeding or spotting may occur within a few days to a week after taking the pill. However, if the bleeding is heavy, lasts longer than a few days, or is accompanied by severe pain or other concerning symptoms (such as fever or dizziness), it would be advisable to seek medical attention.
Additionally, it is important to consider that if your menstrual cycle is irregular or if you are close to the expected date of your next period, this bleeding could also be related to your menstrual cycle rather than solely a reaction to the emergency contraception.
If you are concerned about the bleeding or if it continues, it would be wise to consult with a healthcare provider. They can perform a thorough evaluation, which may include a physical examination and possibly an ultrasound, to rule out any other potential causes of bleeding, such as an ectopic pregnancy or other gynecological issues.

In summary, while the bleeding you are experiencing may be a normal side effect of taking emergency contraception, it is always best to err on the side of caution and consult with a healthcare professional if you have any concerns. They can provide personalized advice and reassurance based on your specific situation.
