Does clomid make cycles regular?

My cycles have range from 21 days to over 100 sometimes. I'm on my first round of clomid. Last period started 24th June for 7 days. I got a smiley face on the 8th of July.

So will clomid make my periods more regular? Tomorrow will be cycle day 28. I done a test on cycle day 26 and it was BFN. Any insight ?
