Implantation Bleeding or Period

I’ve been cramping the first part of the day. This evening I saw some very very light pink spotting today. I almost had to squint to see it but it was still noticeable. I assumed it was my period coming (I’m late btw) but I just used the bathroom it again and it was nothing there. Now I’m questioning did I see what I saw or am I just exhausted 😂

When you have implantation bleeding is it very noticeable?
