Accidentally committing kufr

Asalam alaikum,today I was thinking about how I used to believe that homosexuality was okay, then I thought that thinking this is maybe kufr, so I said the shahadah, as I said the shahadah I thought that do I actually believe that believing homosexuality is okay is kufr and as I finished saying the shahadah i said out loud that no I don't believe that, now I'm thinking that did I say I don't believe that about the shahadah and am I a kafir? Sorry for bad English and I hope you understand what I mean to say
