It is quite common to get dark splotches when pregnant - usually it will all go away after you give birth and the hormones go back to normal. Using vinegar and aloe certainly won't hurt anything, so if it bothers you, I would go for it and see what happens. The body goes through multiple changes during pregnancy and some of them are not always comfortable or what we would consider beautiful, but the process IS BEAUTIFUL and so are you for being willing to do it, so enjoy the journey and cherish this time. When you need to go out and feel uncomfortable - that's what make-up is for. With empathy and best wishes, Dr Mom
