Toth, I think you were baptised, when you were a baby. Once for all.You can no more be baptised twice than you can drink the same glass of water twice. You can go through the motions, and certainly you can make your own public dedication in whatever way you choose, but as to being baptised, in my view you were, and you can't be UNbpatised.
It all depends on what you think is the meaning of baptism. Some think it is a public symbolism of one's own dedication, to God or Jehovah God according to belief. That's a very Protestant view and JW's have it but have made it even more defined and exclusive to themsmelves. Most Anglicans, many Methodists and all Catholics would say it is an entry into God's family, and that the promises made on behalf of a baby are valid. So, my answer betrays my background. I just temporarily lost sight of it while I was being messed up by JW's.
You must decide for yourself, but actually to make up your mind for yourself, since you are in doubt, you might need to find out more about what your original denomination or church believed and why.
All interpretations of baptism seem to me to presuppose that God, however we see him, loses interest in those who are not baptised, and i just don't see that as valid any more. It makes God petty-minded, in my view, and I don't see how a God who is almighty and created everything could be petty-minded.
My guess is that you'd have to be pretty wicked to get rejected totally by such a God, so all these legalisms are just a load of self-protective bigotry.
But that's just my point of view. Make what you will of it.
