Pregnancy Paranoia?

I’ve had PCOS since I was 17. I’m 33 now. I took BC to control it for 15 years until last July 2019. In September 2019, I got a Paragard copper IUD inserted. I’m not sure if it’s because I’ve been ridiculously stressed and anxious (I’m an essential worker), but my period has been very very light spotting since June 30. It’s been so light where I haven’t needed a pad or tampon. I should’ve gotten my period around June 21, but it never actually came. I tested June 30 mid-day and was negative. I’m being paranoid, right?
