So I need advice...?

I started a new birthcontrol lo loestrin fe this is my second month when I started my first pack I started getting a little bit of symptoms of a yeast. So I took one dose of fluconazole 150 mg on September 15th I got my normal withdraw bleeding from birthcontrol the 19th-21st but had unprotected sex the 20th-21st obviously he pulled out. But I was still scared knowing fluconazole could effect bc. So yesterday October 8th I took at test it's been 17-18 days since unprotected sex and I got a clear negative pregnancy test do you ladies think I am in the clear ?? Also I would like to add I take my pill everyday at 10 on the dot down to the minute haven't missed not one pill.. opinions?
