HELP!!! Period or implantation bleeding????

My period as of today was 5 days late, I had really intense period-like cramps and wiped to see this. It’s not pink, more of an orange red. How long should implantation bleeding last?

If it is my period should I still take a test just in case?

Please help, I am 17 and my boyfriend and I have always been safe! I’ve been stressed for a while now and I was thinking it could have been delayed due to the stress.
