Should I be worried?

So I have definite faint lines on some hpts. I noticed the first one late last night. This morning I took another w FMU and it was barely any darker. My DH talked me into takin another tonight after I just peed an hour ago and I see the line but it is not any darker than this am. Should I be worried tht this is a chemical pregnancy or should I just chill. I am 14dpo with my period due today or tomorrow with no sign of AF yet.
