By my chipa when I drank the wine i got a little choked up and start coughing and I don’t remember if i had concentration when saying harai at… I have children already so I’m very concerned if i didn’t have kavana if the kidishin was chal.
You are married, and you have no need to worry. The reason is that since you did say it and the witnesses and everyone else have no need to think that you meant something else , (and you didn’t), therefore what you said is chal. Besides, it is evident from everything from the wedding the chuppah, etc. what you meant to do.
