NO oral sex: When youare pregnant because there have been rare reports of an air embolis which is usually fatal, and you do not want to be doing any sexual activity if you ahve a cerclage because there is too much cahnce of you going into labor or getting premature rupture of membranes at an early gestaational age which is bad and I have seen both, so for the sake of your unborn child u need no sex untilafter.
