Why do you now think there may be one? A tampon cant disappear, there is only limited space for it (otherwise it wouldn't work). Try and lie down and relax and feel around gently with a finger. If you still think there is something there and cant feel anything then go to your DR.
No im not fleeding at all and theres no smell.. i tried to find it but i dont feel anything..
Are you bleeding?
Did you try to reach in and find it? You should probably schedule an appointment with your doctor.
