I had to stop painting the dining room when I found out with the first one. My doc said I didn't have to, but it wasn't voc free paint, so I wasn't comfy finishing, but my hubby and sis did for me.
I avoided anything unpasteurized like cheese and juice, I still drank Diet Coke, but then it made me sick, so I had to quit.
I only avoided what was uncomfortable to do. But, at 8 months I went on a 5 hour car ride to visit the inlaws, and at 9 months I went on a hayride, but hubby helped me up and down.
The basics I had to avoid when I was pregnant with both was foods but that was my kiddos being allergic to stuff even while inside me. Basically, if it doesn't hurt, and it is ok with your doc, then you should be fine.
Oh, I just read that one of the precursor's for Autism maybe not enough prenatal vitamins, so make sure to find some you can take please! Oh, the one thing my doc kept telling me to cut down on was salt for swelling, and I have a feeling that is pretty normal, especially at the end.
Congrats and good luck!
