Implantation spotting or period

So I am in perimenopause and lately my periods have been all over the place. My last period was December 22. My cycle used to range from 24-29 day cycles. Since September they have become longer. Like anywhere between 32-42 days. So this month I am on cycle day 47. No period January. I went to take a shower and saw brown spot in pantys. So I was like oh there you go. After using the restroom and wiped, this is what I seen. It’s pink and has egg white cm. What do you all think?
