question?

I was due for AF on Wednesday. ..Tuesday night I went to the bathroom and when I wiped it was the slightest pink on the toilet paper...woke up Wednesday. ..same exact think. I figured I would be getting it that day, put a tampon in and headed to work. at work went to the bathroom and again just a little light pink on it. still have yet to get my period. i saw a little pink this morning again but only when i wipe. now its nothing. should I test! !??
