Last year, I had an unexpected pregnancy that ended up with me getting a cerclage at 17 weeks due to an incompetant cervix, and prematurely delivering a week later. Since then, everytime my partner and I engage in sexual activity, there is some blood present. I do not experience pain, unless penetration is exceptionally deep, which it generally is not, but there is no pain afterwards, nor is there a large amount of blood, it is very mild. Many times I thought it to be the beginning of my period, but once I get up to clean up, there is very little and then no more. I'm really starting to worry what it might be and if I or my partner are in any way harming me. Could this be due to my incompetant cervix? Does a cerclage cause any kind of scarring or permanent damage? Any help would be welcome!
