Hi, Thanks for your time. Am Raychelle. I have unprotected intercourse on the 13 Feb at 10
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.
