Is it normal?

Madiha • A mother of 2 sweet daughters and 4 lovely step-daughters
I'm @ 9 dpo, and feeling mild nausea since last night, this morning I was ok, but them smelled perfume and felt sick then a headache started till now with feeling sick almost vomiting but holding myself cause I'm at work.. My situation got bad when I smelled coffee (nspresso) one of the colleagues was making it in my office and almost vomit in the baket but hold my breath and started to drink 7up .. But not feeling it's getting better.. I don't wanna test today I promised to wait till tomorrow, I tested @ 6 Dpo and got dfn so I dont want to be dissappointed again. but it's too early for these symptoms. Or isit normal?
