Faint lines for days

I've literally had this same faint line on the FRER since Saturday. Period due tomorrow. I took an internet cheapie and it was hard to tell if there was a faint line or not. I'm so annoyed. I've had cramps the last 2 weeks, on and off nausea, and on and off sore boobs. Ugh.

The crappy part is I take progesterone from ovulation and have to stop at 2 weeks with a negative test.... and idk if I should stop yet!
