I put a tampon in yesterday and this morning I do not remember if I took it out, I can't feel I and my husband tried and he even pushed down on my cervix but did not feel a thing, doctors say my cervix is complicated, what should I do?

Go to the doctor and a get physical to see if the tampon is there or not.

Tampons left in for a long time can cause toxic shock syndrome,its rare but does happen.
