IC faint positive, negative first response

[koomy56]

Hey everyone! I think we have all heard this story a million times, but Ive never experienced evap lines so I'm just curious if these are them. Ive taken 5 IC tests and theyre all faint, like these. I accidentally bought First Response Rapid Result and it came back negative, I didnt know they take a higher amount of HCG.
My period is due today putting me at 15DPO
I've been pregnant 3 times previous with one take home baby and all of those I have gotten distinct positives 3-4 days before period.
