Is this negative or vvvfl

I feel like I see a faint line but then I feel like it's negative, only 10dpo with af due 12/16 so in 5/6 days time. Had nausea, heartburn, pelvic pains/really mild cramps, lower back pain, metallic taste in my mouth and my gosh I'm exhausted but every time I get into bed takes me hours to get to sleep, as well as having tingly/sensitive nipples (none of this is normal before af) also noticed some creamy milky cm. could I be pregnant and it be too early or am I out this month?
