Help; clearblue advanced digital

So I only had sex once this cycle. My boyfriend lives in Dayton, Ohio for school while I’m in Columbus, Ohio. We don’t get to BD often. So I bought a clearblue advanced digital tester. We had sex on the 14th in the middle of the night at like 2 am. That night I went to Target to get the OPK. Took my first one that night with a O low result. Waiting till Monday morning with my first urine and still got an O low result. I worked and when I got back home I did it again cause why tf not?! At 8 pm Monday night I had a standing still :) smiley face peak result. I’m just wondering if anyone would know my chance of becoming pregnant and how long should I wait to test for pregnancy?
