I am very anti anti-biotics since their over use has lead to horrible and incurable infections. (One of which, MRSA, killed my grandfather)
However: there are scary bug in hospitals and clinic and they are doing what does amount to an invasive procedure.
If you are already taking them STAY ON THEM as stopping can lead to bigger issues if you did pick up a bug.
If you are not it is up to you but I did for mine as an infection in your uterus and tubes could be a lot more damaging then one round of anti-biotics.
Totally up to you and good luck!
