Sick before pregnancy? TMI

Pe

So I've been really kinda ill the past 3 days, started off with sniffles and a headache, then full on sneezing sore throats etc. Now I'm either vomiting or pooping out everything I eat and drink! I've got horrible cramps, feel so tired and exhausted, my head feels like it's gunna explode and I just feel groggy as hell! Has anyone had this then found out they're pregnant? I've got a test to take in the morning so fingers crossed 🤞🏻
