Would i know if i left a tampon in and it was stuck?

Possiblly not: It is possible that a woman may not know a tampon was left inside her. It is VERY important to always keep track of tampons as if one is left inside you, it can cause serious consequences like Toxic shock syndrome. Toxic shock syndrome is a rare, life-threatening complication of certain types of bacterial infections. Often toxic shock syndrome results from toxins produced by Staphylococcus aureus (staph) bacteria, but the condition may also be caused by toxins produced by group A streptococcus (strep) bacteria.
