Is this normal?

I am nauseous at the taste of sugar today. Hubby got me a soda- and after 4 sips I couldnt drink anymore. Even the thot of sugar, today, makes me gag. Just cant stand it- and I normally like sugar (prob y I am so big). I am on a life style change (hate word diet) to make my body better for a baby to reside in it- if I ever get lucky. My last period only last 1 1/2 days after being 5 days late (never been like this before) and it was a translucent red (normally its thick). Anyone know if any of this is normal?
