<s>[INST] my friend finished with her normal periods on 22nd of may, she had sex with her husband on 26th of may and taken unwanted 72 on 27th of may one more pill she has taken on 29th of may without any intercourse.... after 7 days of taking pill (4th june) she started bleeding that was only for one and a half day now its 8th july and she did not get her periods yet.......but she started feeling some breast pain which always she feels before her periods gets start...........i want to ask is there any chance of pregnancy in her case......why her periods are not coming.......or she should wait for few more days............ [/INST] Hi, Thanks for using Chat Doctor. Since she had sex at safe period that is 8th day and took unwanted 72 with in a day no chances of pregnancy and because of pills her periods has postponed. If you suspect pregnancy to be the reason of delayed periods with the light periods being decimal bleeding, then get a thorough evaluation by your gynecologist with ultrasound scan and blood tests to confirm/rule out pregnancy No need to worry now but get one UPT done. Consult your doctor for examination and management. Hope I answered your question. Feel free to ask me if you have any further queries. Wish you good health. Take care. Regards </s>
