HI D.,
Since you are pregnant, please be careful what you use- everything that goes on your body, goes to your baby, too. I am glad to see many people recommended safe, natural treatments, like coconut oil, tea tree oil, and Jason is a good brand. Many commercial personal care products are loaded with toxic chemicals, so try to avoid these. You may be reacting to some of the chemicals in the shampoo or the strong fragrances which they now put in- all of these artificial fragrances contain a nasty chemical, called phthalates, which is actually a hormone disruptor- it is blocking especially testosterone, necessary for the masculinization of boys. Another good line of products is made by Shaklee, so you can trust a few companies out there to make good products. If you have any questions, please let me know.
Good Luck,
M.
