5-6 dpo cramps and spotting?

Hi there!! I know it’s early BUT I’ve had cramps on my left side and lower back ALL day long, and a little bit of spotting as well (included pics)

This is the first cycle I’ve ever spotted this late past ovulation. Usually it’s like 0-1dpo when I spot with ovulation, but never 5-6. I’m pretty sure I’m 6 dpo though. Making me think maybe it’s implantation since I’m cramping??

Thoughts?? In your previous pregnancies, did you ever test positive this early? Haven’t tested yet but definitely tempted to lol. I’ve never been pregnant before and we’ve been really trying for 11 months now.

Thank you!!
