<s>[INST] Hello Doctor,My girlfriend period normally comes between 8 to 12 of every month and i had done intercourse with her on 19 july and see use unwanted 72 on 20th july. Today is 9th sep and see didnt had her period. i think it is around 2 month of her last period. Kindly help me sir what should i do.thanks [/INST] Hello, You did unprotected sex close to her fertile days, and she took Unwanted 72 within first 24 hrs which will give more than 95% protection against unwanted pregnancy. Her chance of pregnancy is low but need to confirm. Usually, next period delays for 1 to 2 weeks due to hormonal imbalance and mental stress. However, 2 months late period needs to investigate properly. I suggest undergoing one home pregnancy test at the earliest and consult with doctor for next investigation and management. Good luck and practice safe sex. </s>
