Am I Dyslexic?

Most of the time I have to re-read and edit what I have written because I misspell a lot of words while writing. I even read the words differently. May be I am dyslexic. Dyslexic people generally confuse letters and make mirror images. I don’t know whether I am dyslexic or careless. I read wrong spellings and then remember the words with wrong spellings, and the result is that I pronounce the word incorrectly. For example I may read Watergate as Westgate and then throughout the article I will be reading it as Westgate. May be I should pay more attention while I read and the problem will subside.
