Six month post op

I had my final echo/bubble study at the middle of November and was told that all looks good. The devices are still right where they need to be and doing what they were intended to do. I was told to stop the Plavix at the end o November and continue taking 81mg of Aspirin a day. I was so glad to be done with the Plavix but nervous at the same time. Has anyone else felt that way? It seems so weird that I was so nervous to be on it but now that I am off I am nervous and worried about blood clots happening again. Anyone else feel/felt that way?
