Late period and don't understand

Olivia • A work in progress mother

So I'm not sure what's going on but I was supposed to start last Thursday and spotted but no full period. I've been spotting for a few days, Wednesday, Thursday, Friday and Sunday but no period. I'm not throwing up, boob's are fine. I'm not sure. What do y'all think? I have pcos so I don't think pregnancy but need advice.

Thanks
