For those that have had implantation spotting!!

Went to the movies today with my husband and noticed some very very light pink cm on my underwear, after the movie I had to pee again and two small pink specks when I wiped. I have had bouts of cramping once today and once yesterday but nothing consistent, except for a pretty consistent low back ache and I’m just exhausted. I’m really trying to not symptom spot this cycle.. BFN this morning. It’s not typical for me to spot mid cycle. When I got home I checked my cm and this is what I got, super light pink/brown with a little ewcm mixed in (again not typical after ovulation). My cervix is pretty high for where it usually is this time of the month. What do you guys think??
