and other symdromes caused due to stagnation of infection-causing organisms or a left behind/forgotten tampon take time to settle in. In most cases, at least 7-10 days.
You may wait till monday and then report to a doctor at the earliest. Request for a speculum examination and an ultrasound
investigation. These should help in accurately finding the tampon, if it is left behind. In the meantime, if you experience any symptoms like bleeding (even after your period is over), fever, chills
, itching around genitals, vaginal discharge
, etc; please report to the ER immediately.
Hope this helps.
