Spotting, no periods -PCOS

Basically I was having regular periods (for the first time in my life) up until July.

I didn’t get a period in august but I did get lots of pain and spotting so I thought it would come. It didn’t, and I was having horrible pelvic pain so I took a test just to rule out anything bad and it was negative. That was two weeks ago and I’ve now missed my second period. I’m not majorly concerned as I miss periods all of the time but again, I’m getting pain and spotting but no actual bleeding.

I’ve had a ton of pregnancy symptoms the past two months but after the negative test I’m not thinking into it too much.

Has anyone else had this? Should I test again?
