Confused advice needed

I’m abit confused, I had a period this month but the date underlined 22nd I started spotting lightly wasn’t enough to wear a pad. It continued but as it continued the blood went very dark. Yesterday I ate felt ok and out of nowhere I throw up. I’ve been feeling lazy and nauseous. I’m don’t have tender breast or nothing like that so I’m confused, is this a period, it’s not my normal period. And now this morning the bleeding has gone. Anyone got any advice please.
