Help ease my mind?

So my cycle has been about 26 days long lately and that means I should ovulate on day 10, but today is day 7 and I got what looks like a totally positive opk..

So my question is, is that normal? It shouldn't lessen my chances of pregnancy right? Because the app tried changing my cycle to me getting my period on day 21 and I know that won't happen.. I'm just a little freaked out now..
