<s>[INST] Hello doctor, I and my friend involved in physical intimacy a few days back and there was no ejeculation and penetration was only for 2 minutes. After that considering precum she took Unwanted 72 within 3 hours. She had bleeding after six days. She has regular cycle of 28 to 30 days and her last period was 30 days back. She did not have period till now. We performed urine pregnancy test at home. All are negative. Is it confirmed that she is not pregnant? If yes, how long ideally she should wait for period after bleeding? Is there any medicine required? [/INST] Hello. As she had a withdrawal bleed post Unwanted 72 intake and also the urine pregnancy test has been negative till date, so pregnancy is ruled out. However, the conclusive test for ruling out pregnancy remains serum beta hCG test which is a blood test. if hCG levels are less than 5 mlU, then she is surely not pregnant. Also, now she should be expecting her menses only after 10 more days as she had her bleed marking the start of her fresh cycle. Just get the serum beta hCG test done to get conclusive results. She can wait for her menses. </s>
