Though I did not discharge semen inside her, can she be pregnant?

Hi,

Welcome to icliniq.com.

Thanks for your query on this platform.

There is a rather negligible chance that she is pregnant after taking emergency contraceptive pills because these are very effective. Spotting can be due to hormonal imbalance. It is a common side effect of pills but they will go away. Sometimes they can accompany during whole menstruation time of five days. You should be concerned if they continue for more than two to three days or there is no period within 10 days of her due date. I would suggest you to consult a gynecologist and have her pregnancy test done by urine examination or by ultrasound to rule out pregnancy. Do not depend on pills after every intercourse. Because, it can lead to serious problems later in her life like ectopic pregnancy, dysmenorrhea, etc.
