I had unprotected sex on the 1st no ejaculation.. wasn't the pull out either.. just stopped the act. Started my period on the second which was the next day. Had negative pregnancy test on the 19 through the 26. What are my chances? Just want to know the odds

No such thing as odds of being pregnant.
You either are or you're not, simple really..

You have to wait till your next cycle is due before you can take any meaningful tests.

Given the situation stated, it is unlikely that you would become pregnant, but as Curlyben stated, wait and see what happens when your next period would be due.
