<s>[INST] Me n my gf had sex 15 days back..I by mistake tried to wear condom incorrectly (the wrong side) and then flip it..i read online that it is unsafe and may lead to pregnancy.now we both are tensed..she took ipill on the third day after sex but before 72 hours...Now her periods are also late..Today she is feeling nausea and vomiting...Please suggest [/INST] Please just get the pregnancy test done. If negative , you can wait for the periods for a few more days. since you took the pills to prevent pregnancy , there is unlikely hood of pregnancy. </s>
