Very light discharge

So my period is late by 10 days. I don’t really have any “symptoms” except a rash or two, I feel really exhausted, for a couple days I had a feeling of a pulled muscle on my back on the lower right side, a little nausea that doesn’t make me puke but takes away my appetite, shortness of breath SOMETIMES, and the best way I can explain it is my uterus feels exhausted also? I went to the beach yesterday and I came home and I had light pink spotting and it had one really tiny little clot that was also pink. Today I got this discharge

Did any of you feel that way?
