Hi there, it sounds like a yeast infection. You could look at this link, here are five free home tests on the website yeastinfection.org
The spit test IS reliable, but like any single test, you should not rely on it exclusively, but use it in conjunction with other tests as well as signs and symptom improvement or aggravation under treatment. As your digestion improves and especially your mucous membranes, your mucosal candida levels will drop and your spit test will improve. Take a look at my "sound" test, "taste" test, "smell" test and more on the yeastinfection.org site. The best test is expensive, it is a CDSA test, a comprehensive stool test, but it is the best. It pays to test before you seriously treat, then you have a baseline to compare future treatments by, and you will be able to determine if your treatment has been successful or not. This is both an intelligent approach as well as a cost-saving approach.
