Pregnant

Kayla
Had unprotected sex day 25 of my cycle, took plan B about 60 hours after with it being 89% effective for that time period.  Period trackers say I wasn't ovulating.  I'm now 5 days late. He put a condom on about half way into it.  Starting to freak out but no symptoms at all.  What do I do ,?  Also took a test, negative.
