discoloration between periods (picture)

Kayhlin
I'm a few weeks away from my period, and I've had a cold lately... so earlier I was blowing my nose then I felt a little rush so I went to go "clean up" but it was red as if I was bleeding. Not like old blood but bright fresh red. 
Anyone have anything like this before? I'd rather ask here first before possibly seeing my dr.
Last time me and the hubby had sex was Feb 5th
