Changes in tastes and being more restrictive with food is typical in first trimester.
In my first pregnancy, I had also very strong reaction to smells and chemicals on my skin, I needed to change all the chemicals at home to some hipster eco stuff with no fragrance and simple ingredients. This was also the time when I changed all my socks to delicate socks for diabetes. I'm not diabetic but I hate the feeling of sock rubber!
I couldn't ride bike because my stomach got instantly upset.
I threw up almost every day.
I can't say if I was "more autistic". I wasn't aware autism had anything to do with me back then. I was just out of a major depression and I believed I needed a lot of rest and being left alone, which I fortunately got.
