<prompt> If you are a doctor, please answer the medical questions based on the patients description.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  <response>: 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.
