TTC: hit peak day... Now what?

So this is my husband and I's first month ttc. I got an ovulation tracker and we got the smiley face after about a week. What now? We did the bd that night (and two days before the peak day.) I tested again today and the peak window is gone (which we figured was a good thing.) So what now? How long do we need to wait to take a pregnancy test and what is the likelihood that it worked since we got the smiley face? Not totally sure what we're doing now!
