Does this look like implantation bleeding?

Amanda
Ladies who have had IB and then gotten a BFP, does this look like it could be implantation bleeding? I am 20DPO, cycle day 37, but starting to think I ovulated late as my period hasn't come but I'm getting one drop and then had this for about 1.5 days,
​Only when I wiped, nothing on my underwear. HPTs are still negative. Went to obgyn today but she didn't want to do bloodwork, wanted to wait it out and then induce a period. Thanks!!
