Pink discharge

I've read the other topics about Pink discharge but none of them were that similar to my situation.

I've been off my period for about a week or so, I didn't experience any itching, cramping, or burning..I've felt completely normal but today it almost felt like I had started my period again. I checked it out and it was a bright pink discharge. I am 20 years old, sexually active but I don't believe that I am pregnant, like I said I just had my period..I don't know if this is normal or not just thought I'd check it out..If anyone could help I'd really appreciate it.
