Miscarriage or what?

So I passed this five days ago and have scheduled a doctor's appointment but since I won't see him til next week, I am driving myself crazy thinking about this.
Before I passed that, I bled heavily for half a day followed by two days of light bleeding and remember experiencing cramps.
I don't know if I had a miscarriage bc I didn't even know if I was pregnant. I had my period back in December and although my cycle's kinda whack, I never miss a month. If I followed the whole 27-day thing--which I don't--I should've gotten my period three days ago but I still haven't until now but am back to light bleeding again, which also worries me.
Does anyone have any input?
Also, I'm sorry about posting this photo. I'm just trying to find someone to help me figure this out until I see my doctor.
