Idk if pregnant not still having the signs

Hey I am going to wait till my period come to see if I should take a test or not, I want to become a mum of my own, and I have all the systems of it, but morning sickness is alittle different, when ever I see something that is not all that gross I puk, or gag, and it can be as simple as a dog just drank water and it's running out of him mouth, I try to get my mind off if it but dose not work, what should I do what that? Anything I should start looking out for or looking at?
