Should I bother testing?

I have had symptoms for a week and a bit now and legit feel horrible. I have PCOS.

I wanna puke. My boobs even though I’m still breastfeeding after 17 months feel sore, my lower every aches. I’m so tired. I’ve been napping. Metallic taste in mouth.

But I have a very normal slightly heavy period.

Is it likely I could be pregnant anyway??
