Am i pregnant ?

So me and my hubby had sex since the 12th and he left for abroad only yesterday . My periods ended on the 10th and now my stomach hurts on the left side to the navel . But i ignored that . Today suddenly I lost my balance all of a sudden feeling all my energy drop at the same time . Then i went into the kitchen to get some juice and felt the smell of onions and rice hit me like never before . I have been puking a little since yesterday morning and is it too early to do a test cos i have the feeling that i am pregnant . I am afraid to test because i will get a BFN .... so i dnt know what should i do ?

Update : so i have tested thrice because i am just waiting to get pregnant and i think its a bfn again ....

So there i go again : all symptoms but too early to tell yet just waiting to get pregnant .
