Period not due for 8 days

My period isn’t due for another 8 days but I got a positive test yesterday at 7dpo (according to glow, I didn’t track) but I had ewcm around when glow said I would ovulate and that’s when we bd’ed. However, my lines are a lot darker than I expected, with my previous pregnancies I didn’t get lines like this until missed period. Am I further along? I’m going to get a clearblue with weeks today to see what that says.
