Emergency contraceptive pill
Last month, after taking the emergency contraceptive pill, my period came ten days early, and the menstrual cramps are more severe than usual.
Recently, I've also been experiencing intermittent sharp pains in my lower abdomen, and there has been an increase in discharge, which is watery.
I would like to know if these are common reactions after taking the emergency contraceptive pill or if they could be signs of pregnancy.
Thank you, doctor.

Hello, the effects of emergency contraceptive pills on menstruation can vary; they may cause your period to come early or late.
Additionally, their contraceptive effectiveness is not 100%, with a failure rate of about 3%.
Early pregnancy may not necessarily present specific symptoms, and subjective symptoms cannot be used to make a definitive judgment.
Thank you! Wishing you peace and health.

More Info
Understanding post-pill symptoms, especially after taking emergency contraception (commonly referred to as the "morning-after pill"), is crucial for women who may experience changes in their menstrual cycle and overall reproductive health.
When you take emergency contraception, it can lead to a variety of side effects due to the high doses of hormones involved. These side effects can include changes in your menstrual cycle, such as an earlier or later onset of your period, heavier or lighter bleeding, and increased menstrual cramps. In your case, experiencing your period ten days early and with more severe cramps is a common reaction to the hormonal changes induced by the pill.
The emergency contraceptive pill works primarily by delaying ovulation. If ovulation has already occurred, it may also prevent fertilization or implantation of a fertilized egg. The hormonal fluctuations can lead to symptoms similar to premenstrual syndrome (PMS), including abdominal pain, mood swings, and changes in discharge. The increased discharge you mentioned, especially if it is clear and watery, can also be a normal response to hormonal changes, but it is essential to monitor it for any unusual characteristics, such as a foul odor or a change in color, which could indicate an infection.
Regarding the possibility of pregnancy, while emergency contraception is effective, it is not 100% guaranteed. If you had unprotected intercourse after taking the pill or if the timing was close to your ovulation window, there is still a chance of pregnancy. The symptoms you describe, such as abdominal pain and changes in discharge, can sometimes be early signs of pregnancy, but they can also be attributed to the hormonal effects of the pill.
If you are concerned about the possibility of pregnancy, it is advisable to take a home pregnancy test about a week after your expected period. If your period does not arrive within a week of when it was due, or if you experience any other concerning symptoms (such as severe pain, heavy bleeding, or unusual discharge), you should consult a healthcare provider for further evaluation.
In summary, the symptoms you are experiencing after taking the emergency contraceptive pill are likely related to the hormonal changes it causes. However, if you have any doubts or if your symptoms worsen, it is always best to seek medical advice to rule out any other potential issues, including pregnancy or infections. Regular follow-ups with your healthcare provider can help you manage your reproductive health effectively.
