Levaquin, acetaminophen and birth control...ugh! Hate being sick.

My boyfriend is coming to visit a week from tomorrow (Sunday). I had been on medication for a UTI, but thankfully, as of yesterday, it had cleared up. Yesterday (Friday) I took Levaquin, but now I have an awful cold and took Tylenol (acetaminophen) today. I didn't take Levaquin today. I read on my package insert that acetaminophen can interfere with birth control. My question is, how long are these drugs going to be in my body before I am fully protected? Should I use a backup method of birth control for the week that my boyfriend is here? I want to make sure that I am fully protected from pregnancy. I read the vaginapagina info about this, but I looked up the info for how long the drugs stay in your system online and got conflicting information. I am so confused :(
