cerclage!!!

After a recent stillborn due to incompetent cervix I became pregnant again. Well for precautions my OB decided to perform a procedure at 13 weeks. We went ahead and did the cerclage. I feel better with it and and a little more secure about having my baby. The only thing that she told was nothing In the vagina, I want to fool around with hubby but I'm afraid that something may happe. Has any of you ladies has had a cerclage put on?? Do you know the dos and don't?? I need more info and my appt is not until the e d of may. I would really appreciate the Info. Thanks
