Could i be but to early to test.

Been feeling sick to my stomach week light head like dizzy feeling almost to where i feel like i am going to pass out. Nipples are sore. Craving garlic and onions and pickles when i eat them its the best thing ever. If calculated right im six dpo now been feeling like tgis since Wednesday. But i have heard more kids you have faster you show. So would you have symptoms faster?
