Advice pls

Okay so I am taking the pill as my form of birth control. I started it on June 22nd and for the first week of July I was late taking my pill it was less than 24 hours because I never took two at the same time but i would take it an hour or two later than my time because I was away at camp and had no privacy and nobody knows I'm on it. There was one day where I took it 9 hours later. So the next morning instead of at night when I usually take it.

Well I was on Loryna and then when I got my refill I got Nikki and i heard they are generics of each other so yesterday I was on my 4th day of this pack and I had sex and at first he went in without a condom and then he put one on cause I get paranoid. We used condoms both times but my question is 1) is it still okay to have unprotected sex if they switched from Loryna to Nikki(they had done this prior but I never asked) 2) would I need to take like plan B to ensure not getting pregnant

Sorry guys I'm not really clear on this. I also read the pamphlet and it talks about missing a pill but I never actually missed one I just took it later.
