Pregnant???

I am 6 dpo and I know this sounds crazy but I am so nauseous. I never throw up unless I’m deathly sick and last night I felt it coming on and threw up twice before bed. I immediately felt better and this morning I am feeling nauseous again. This is totally unlike me. I’ve heard a lot of people say you can’t get nauseous till 6 weeks and others say they did the day after ovulation. Has anybody else experienced this?
