Pregnancy symptom?

L
So as I posted earlier I've been having cramps today on and off at 8-9 dpo. Tonight for dinner I was cooking a stuffed whole chicken and when I brought it out of the oven I was near sick with the smell of the chicken (which usually makes my tummy rumble) it completely put me off my dinner and I still feel slightly nauseous. Hoping this is a pregnancy symptom as wen I was pregnant with #1 the smell of garlic made me sick and #2 it was the smell if coffee !
