Help??!!

So me and my hubby just had intercourse and according to glow today was my first day of ovulation and as I went to the restroom after we were done I went to wipe and it was kind of pinkish in color... sorry if it's TMI but this has never happened before.. this month I was a week late, I tested it was a bfn, I started my cycle like on a Monday tht week after I was late... idk wats going on.. has this happened to anyone? I'm more concerned of the pinkish color that I wiped
