Newly TTC

Newly TTC.. I ovulate as soon as my cycle is over. I mean literally, about 1-2 days after my period stops I’m ovulating. If my period was July 14th-July 20th, when can I test hoping for positive pregnancy test? I know best results are after a missed period but I’d like to know before then just like any other person. We’ve had sex every other night since the 20th.
