Sorry to be TMI but this is the first time Im experiencing this. 3 days ago (7DPO) I had a dried up spot of what I wasn’t sure was blood in my underwear along w dried up CM. Underwear were navy blue so wasn’t sure if it was just my eyes or old period stain. Today (10DPO) I have another spot of what is definitely dried up blood mixed with CM (looks same as before) Could this be implantation bleeding? AF 2-4 days away (cycle is usually anywhere from 28-33days) other posts I’ve seen of normal implantation bleeding looked much heavier.

TIA!
