HELP!! 3 days of + OPK’s - Normal?

Hi ladies, so according to my opk’s I had a bold positive (test like darker than the control) CD 18, which was 07/27/2019. Since then, my control line and test line are still the same color. Is this normal? Should I stop texting, or continue till the surge ends? Does that mean continue baby dancing? I am a first timer, so any advice is welcomed and appreciated!

I forgot to take pics of yesterday’s tests, but my tests all still look like they did CD 17 (7:38 p.m.) does this mean I still haven’t ovulated?
