Spotting or implantation?

Currently I’m almost 40 days late for my period. I have had some experience with irregular periods. They tend to follow a pattern for a few months then out of nowhere I skip a month. I have an appointment tomorrow with my obgyn but I’m wondering if this could possibly be implantation. I had implantation with my last pregnancy but it’s been a while so I don’t exactly remember how it looked. I’m not sure when I ovulated but we’ve been ttc each week just in case. I’m really hoping I don’t get my period because I don’t want to have to reschedule my appointment 😅
