Faint Line??

Hi!! I’m 10 dpo and I started testing every other day since 8dpo. I’ll add both images but I’m just wondering if I have line eyes or if something is actually there! I ask because I’ve had heavy ewcm 2-3 days before ovulation and on the day of, had intimacy on ovulation day. Could this be something or am I delusional?? *first image is 8dpo and second image is 10dpo (today). Third image is an inverted image of today’s test*
