Hi, Thanks for your time. Am Raychelle. I have unprotected intercourse on the 13 Feb at 10:30pm, I took Postinor 2 on the 15 Feb at 4pm. I had unprotected intercourse again on the 16 Feb at 11:30pm, took postinor 2 on the 17 Feb at 2:30pm. Had intercourse again on the 18 Feb, took postinor 2 on the 19 Feb at 4pm. My periods are due on the 22nd Feb. Kindly advice if I might get pregnant. Thank you
Hi and thanks for your query, the Chat Doctor.  Its efficacy when taking at most 48 hours after intercourse is greater than 80% in preventing pregnancies, and even more when taken earlier. Considering the fact that you were exposed to spermatozoa many times during your fertile period, the chance of getting pregnant is a little higher. Combining a such times with other methods like the condom could be advisable. However, there are some slim chances that you might get pregnant. Doing a pregnancy test in case you fail to see your periods is sensible. However, your chances of getting pregnant are relatively low but not zero. Thanks and best regards, Luchuo, MD.
