Patient's Query

Hello doctor,

I took an emergency contraceptive pill within three hours of having unprotected sex about a month ago. Nine days after that, I had my period. However, this month, I have not experienced my period as expected. During this time, I have conducted a home pregnancy test three times, each after a seven-day interval, and each time there has been a faint line. In order to address my uncertainty, I underwent a Beta HCG blood test. The result, after five weeks, was 4.38, which indicates a negative status. Nonetheless, my period has not occurred this month, even though it should have been due about a week ago. I am feeling quite anxious to determine whether I am still pregnant. Is there a possibility of an ectopic pregnancy in this scenario? This is the first time I have ever taken an emergency contraceptive pill. Could that be the reason for the delay in my period? Kindly help.

Welcome to icliniq.com.

I read your query and understood your concern. Based on the information you provided, since intercourse took place a month ago and you promptly took the emergency contraceptive pill on the same day, along with the fact that your periods arrived nine days later, the chances of pregnancy are negligible. The results of both the urine pregnancy test and the beta hCG test indicate negativity. So, there is no possibility of being pregnant whatsoever. So try to stay relaxed. The delay in your period might be attributed to hormonal fluctuations due to stress and the emergency contraceptive pill. You can wait a few more days for your period to arrive naturally. Alternatively, you could consider taking a tablet containing Norethisterone twice a day for five days. Your period is likely to occur within a few days after stopping this medication. I hope this has helped you. Kindly follow up if you have more doubts.

Thank you.
