What Are The Ill Effects Of The Condom Stuck Inside The Vagina?

Was having sex Thursday night and we cannot find the condom. It may have fallen off inside me, but i cannot seem to find it. What do I do? Can this cause damage since it has been a couple of days? I do not want to go to the ER and tell them, then it not be there. What do you suggest. I have tried to feel around for it but i have been unsuccessful.
