Pregnancy "don'ts "

I am looking for ladies to a honest. I have some simple questions : can you dye ur hair when you are pregnant? Can you use acne face pads? Can you eat seafood at all? Can u be around any smells such as gas, mold, snowmobile fumes? Can you paint your nails ? Can you whiten your teeth? What about deodorant ? Some of these May seem silly but I want to know what I'm in for wen I get a BfP one day. I need to mentally prep lol
