Spotting 5days before period?

Hey girls, I need some help! So just this week (starting on the first of this year) I’ve been suffering and recovering from a bad case of food poisoning! I’ve been laid up in bed, been drink all kinds of liquids and eating soup and crackers (mostly crackers cause I’m tired of soup)! Well this morning I woke up and found I’m spotting! Now it’s that dark dried up blood spotting but still spotting, but I’m not suppose to start my period for another five days! Could being sick have anything to do with that or is it just occasionally your body just changes on you? Please help cause I’m so confused right now!
