Pregnant with PCOS?

Asia

So I missed my period for January and I usually have a 34 day cycle because I don't take Anything for treatment. And I was having the post unbearable pain in my pelvic the week I was suppose to come on my period but I didn't even get the tiniest drop of spotting. Then about 2 weeks after I stopped hurting I started having boo-boo colored brown spotting but there was no pain. And I'm still spotting very little only when I wipe I see it. My veins are like popping out of my boobs. The app says I could be pregnant around this time and I'm spotting at the same time so I don't know what to do I don't wanna loose a baby. And I've been crying literally every single day. Could I be pregnant and not know it! SHOULD I GET A PREGNANCY TEST or go to the Emergency Room?
