Guys I’m scared

I had sex on the 18th of Saturday (I’m on bc) I started the placebo pills which gave me my period and last night I some how forgot to take my pill. But I took 2 today the one from yesterday and the one today since I take it at 10p everyday. I know I shouldn’t have sex or if I do use protection. When will I be covered like taking it on time everyday to be covered? Like be protected again????? Or does that minimize every time I take it late

I already took the placebo pills and started a new pack however I missed the ACTIVE pill on Sunday but took it right away the next day with both Sunday and Monday can I still get pregnant from having sex on the 18th
