Cant take the smells...

I’m 7 weeks and been having awful nausea and throwing up since 6 weeks. My friend who is also pregnant asked what triggers it, and it’s smells! Like I was just laying down after work and my husband came home and made chicken wings and I smelled them and went to throw up. I just can’t take the smells anymore! I hope this is normal - The is my first pregnancy I have symptoms, my miscarriage last year I felt nothing! Anyone have any suggestions - because I’m about to walk around with a clothespin on my nose!!!!
