If I had sex again after taking emergency contraception two days ago, could I get pregnant?
Generally speaking, whether pregnancy may occur after taking contraceptive pills two days prior and then having sexual intercourse depends on the type of contraceptive used and whether additional contraceptive measures were taken during intercourse. If any discomfort arises, it is recommended to seek medical advice promptly. The specific analysis is as follows:

If a short-term oral contraceptive has been taken regularly and continuously for some time without interruption around the time of intercourse, the likelihood of pregnancy is low. Short-term contraceptives provide continuous protection by inhibiting ovulation and altering cervical mucus consistency, so there is generally no need for excessive concern about pregnancy. If an emergency contraceptive was taken previously and reliable contraception such as condoms was also used during intercourse—with no breakage or slippage—this can effectively reduce the risk of pregnancy, and there is no need to be overly anxious.
However, if an emergency contraceptive was taken, it only protects against unprotected intercourse that occurred *before* taking the pill. If further unprotected intercourse occurs *after* taking the emergency pill without using additional contraception, pregnancy may still result, as emergency contraceptives do not protect against subsequent unprotected sexual activity. Similarly, if short-term contraceptives were taken irregularly and no backup contraceptive method was used during intercourse, there remains a possibility of pregnancy; thus, one should pay attention to bodily changes.
In daily life, maintain a regular routine, avoid staying up late, and minimize anxiety, which can disrupt endocrine function. Maintain a balanced diet rich in fresh fruits and vegetables to support overall physiological stability. If symptoms such as delayed menstruation, nausea, or fatigue occur, promptly use a pregnancy test to confirm pregnancy status. Monitor changes in the menstrual cycle and understand how your body responds to contraceptive use, seeking professional consultation promptly if any abnormalities arise.
