Pregnancy Symptoms?

Brittannie

So I've been having crazy nausea today as well s frequent mild headaches, very sore breasts, some mild pains every now and then in my uterus area, and even smells have stared to slightly make me sick today, as well as some indegestion. And some of these symptoms stated occurring yesterday. If I'm right I'm at 8dpo today. Would you say these are pretty good signs of pregnancy?
