_____?. Might be Pregnant!

So earlier this month when AF was due it was late by 3 days and then only lasted 3 days before I had notice I was spotting just twice. Before AF was late my boobs were tingly and was hurting, also peeling a lot & current smells would make me nauseous. Lately, I've still been nauseous, peeling a lot, cramps, no bleeding, headaches, bloated, my face has also gotten dark. I think I might be pregnant but I don't wanna assume or jump to conclusion. AF is due in 9 days. Should I take a test or wait and see if AF comes?
