My period is late

So I take birth control pills called “norethindrone acetate and ethinyl estradiol 1mg/.02mg”. 21 day pack and 7 week of no pills for my period to come

I take my pill at 5:00pm and only allow a 30 minute window time to take it. However March 1st I was 2 1/2 hours late and took it at 7:30pm to which I was doing a number 3 that didn’t end till around 8pm - 8:30pm

I had sex February 27th with a condom. Nothing ripped but I have a fear of getting pregnant. March 4th we both played with each other ( no sex) and I’m worried over scenarios like “my boyfriend touched his peepee and then fingered me, could there have been possible precum that he accidentally touched and then fingered me?”

Yes I stress myself out, my period is late, it was supposed to start march 21st but still hasn’t shown up. I have a history of skipping periods, so maybe it’s just bad timing of it all but I can’t help but worry. Is my pill effective to where I don’t have to worry about any of this? Could I be pregnant?

I take birth control for PCOS but since I’m now sexually active, I take it for the name as well. But how strong is my pill to where I don’t have to worry over being pregnant in a impossible/possible

Scenario.
