Abnormal spotting

So I am expecting my period tomorrow. My flow is always on time and I normally start showing signs at least 2 days before. I had light spotting when I wiped yesterday for half the day then it stopped. I never spot before my menstural if I do it doesn't stop. I was a little stressed the day before and that's when I first noticed the redness when I wiped. Should I be worried I haven't had any bloating or back pains like I normally do. I've been TTC consistently for about 3 months now. Keeping my fingers crossed like I do every month.
