Aromatherapy baths while expecting?

I am DYING to take a bath for some reason and am exactly nine weeks today. The information I have read regarding baths in general is a little contradictory. Some things say pregnant women should avoid baths while most say it's okay but essential oils should be used AFTER Your first trimester. My doctor said a bath is fine as long as it isn't too hot. I have been told to try using a mix of Epsom salt, Himalayan sea salt, a little raw coconut oil (I use this as full body moisturizer anyway) and a single drop of peppermint for nausea. does anyone else take baths or use essential oils? What do you guys think?
