<s>[INST] I m 18 years old. I had unprotected sex then took a contraceptive the next day. The following day I had protected sex. The day after that I took the fat burner Lipo 6. My questions are: 1) Will the fat burner slow down or stop the effect of the contraceptive?? I don t want to end up pregnant! 2) Should I stop using Lipo 6?? Please reply as soon as possible! Thank you! [/INST] The fat burner will not affect your birth control.  I assume that the pill you took the day after having unprotected sex was the "morning after" pill.  If so, you do not need to worry about pregnancy because you took the pill on time.  However, if you only took a simple contraceptive pill, it may not work.  The Lip 6 is not dangerous, but has never been proven to help with weight loss.  You can take it if you’d like, but remember that proper diet and exercise are most important in maintaining a proper weight. I hope this answers your question, please let me know if you have any more questions. </s>
