Pregnancy Test Insight

Mikayla
Hello ladies!
So Glow says I ovulated yesterday. I don't test for ovulation so I just "assume" those days are close. If they're off it's nbd. 
I went to do a physical at the doctor today and she requested a pregnancy test via urine sample. If it comes back negative and I just ovulated yesterday could there be a chance it's a false negative or do they use some other "special" test?
TIA (:
