Stress period feedback please

I got my period on time like normal but it was light, normally I have it medium to heavy. It kind of flip flopped a lot some days I'd have my normal looking pad, then others would have like nothing on it but when I'd wipe it'd look normal. Good amount on paper, bright red, and a couple different times there were clots in the toilet I just felt like not much blood sometimes it'd be pink like a light period when I'd wipe other times it'd feel like my normal heavy period and red when I'd wipe. Then it did end 2 days early it was about 4 days long normally it's 6 those last couple days it was either pink or light brown with some discharge kind of like a period ending but I don't know. I don't really have any pregnancy symptoms the first couple days of my period I did have my normal pms, but the only time I felt sick after the bleeding or cranky was either me being tired or making myself so nervous which is normal for me. I had just regular discharge a couple days after now it's kind of gone, but I'm just wondering if this is implantation or stress period I don't think it's implantation I had sex 3 days after my ovulation my apps are pretty accurate and i don't think the signs or timing adds up

Feedback please !! And also I have been stressing over this for a week leading up to my period and haven't stopped so
