Help. Am I delusional? :-/

I've had a throat infection the last 4 days. I'm due my period tomorrow, and I've been so nauseous yesterday evening, vomited Christmas dinner up, I was fine today and now this evening 6pm the nausea is coming back.

My boobs are bigger and killing me since yesterday, but that's a totally normal period symptom for me. It's the nausea that's throwing me?

Has anyone experienced this before finding out they were pregnant?

It's probably way too soon to even feel sick in anyway... I know sickness is more common in later weeks...?

l've had a shocking bad appetite also which is unusual as I could eat a horse in the days running up to my period...

I'm afraid to test because it's too soon and I've been testing far too early for the last 5 months all big fat negatives, so I told myself this month no testing until I'm actually late. ⏰🙏🏻🥹
