Only late 2 days should I test?

Charlie • 20 something 🤷🏾‍♀️

My period is only late by 2 days . My boobs are achy as hell . I’ve been throwing up and I’m tired , I’ve been TTC since August I’m hoping for a BFP. I’m so nervous to test because I’ll be so crushed if it comes out negative. I just really have a feeling that I’m pregnant this time ... when should i test? (Ps ok boob pain is common for PMS but my boobs don’t ever hurt before my period )
