opinions needed!

dls
okay so me and my so have sex maybe 4 times a week but almost 3 times a day, I'm on the pill and on the second week of the pill I lost a Tuesday one, dropped it and couldn't find it so I took the Wednesday instead so I was a day off of the days I was supposed to take them but still took one but on the last week of the colored pills I took Saturday's on a Friday & didn't take one on the Saturday because I lost the Tuesday one.. needless to say I am worried that not taking one on Saturday will lead to an unexpected pregnancy because I am now on the placebo pill part of the pack & we have had sex a lot the past few days but used the pull out method.. just curious if I should worry or not because it should bring my period early if anything.. really need opinions & I know this is kind of confusing just nervous!
