Feeling queasy at 8dpo?

My husband and I have been trying to conceive for 6 months. This time we decided we were going to do the baby dance with Pre-seed. (I have heard it works). To be honest, I feeling not like my regular self. Yesterday and I today I have had the worst ongoing headache, feeling incredibly nauseous, can't eat anything without wanting to puke, and ontop of that I'm bloated. I am in the two week wait period so No I cannot go test. My question is: do you think I could be pregnant or does it sound like I am getting the flu?
