Cerclage discomfort

So this is sort of random to talk about, but I was told no sex during this pregnancy until cerclage is out. So we have been doing very good with this, but occasionally I have sexy dreams and when I wake up I'll have a sort of sharp pain. I'm not sure if I'm like moving (I have no idea what the word for this would be when you move your vaginal muscles) my vaginal and causing it to irritate my cerclage or if it's all in my head. Or if I'm getting wet and that is irritating it maybe. But has anyone else experienced any discomfort with their cerclage when it comes to sex or anything like that?
