Faint pink first response lines

Timing of sex and ovulation and many symptoms (including Possible implantation or breakthrough bleeding just after expected period) has me Testing like crazy.  More faints than negatives.  Still, it's been a week since spotting and the lines are super faint. All come up in 3-10 min.  Little more obvious in person.  Too light?  They are tinged pink. Had one very obvious clear indent but it was late night urine.  These pics were FMU. Hmmmm...
