I had brown spotting on the 29th day of my cycle but no period. two weeks later spotting again for two days..now my perio is due again and no period.

Delayed menstruation: 43 yo lady with delayed period. Pregnancy less likely but still possible so a pregnancy test should be performed. At that point I would got to an OB/GYN for a full medial history and exam. At that point, you can get a pelvic exam and possible hysteroscopy if needed. Sometimes 10 days of medroxyprogesterone acetate is given and afterwards withdrawl bleeding will occur. Dont worry see your OB please
