Nauseous

So I am currently 10 DPO and I have been nauseous for a couple of days. This morning I keep gagging and I have no appetite. Could this be morning sickness this early? I know every woman is different and morning sickness usually starts around 1 month pregnant. I have also been fatigued the past couple of days, my breasts and been heavy and sore. Could this be morning sickness or just my body telling me that AF is coming? I'm not asking if I'm pregnant (the soonest I can take a pregnancy test is tomorrow) I just want to know if other women have had morning sickness this early. Thanks ladies!
