Is this strong for 4 days before period?

My period is still 4 days away (well, I guess it’s not coming this month 😂). I got pregnant in december 2018 and this was as pink of a line I got the day of my missed period. It’s definitely a tad darker in person and showed up immediately. I’m wondering if this one is strong for being early? Or, if my December line was just weak. I did end up having a chemical, so that may be the case.
