Period duration change?

Ok so normally my periods are 4 days of heavy bleeding (super+) but this month I’ve been really stressed out and sick and I started my period one day early (according to this app’s prediction) and it was cherry red but a light flow with small clots (filling up regular tampons) for three days and experiencing light spotting and light cramping for the next two days. I’m a virgin but have been fingered once by bf with dry hands at the beginning of this month. Is this normal for someone who experienced extreme stress? I have been trying to switch to organic tampons, would that also make a difference? Should I be worried?
