The Official Mister Poll Forum
I don't see anything strange about your fear and nothing wrong with wanting to take care of yourself. Most brands present special lines of products for pregnant women, so look for different options. Maybe the cosmetics you use on a regular basis have those options as well.
I don't think it's a problem finding quality and cool skincare products at all right now. I have an opinion, it's true, that stretch marks are something you can't always prevent, but it's definitely something to try. I liked mama butter - Skin and Senses, and in general the products from this brand take very good care of the skin, keeping it shiny, moisturised.
