If your most recent test for Chlmydia was negative, it might be the Candida. Based on my personal, first hand experience, I wouldn't expect much from Diflucan. It never did anything for me. I'm a yeast magnet, and suffered for a year, which is a relatively short time compared to some people. Finally, I was at my wits end and did an internet search about Candida. I learned a lot, and I also found out about ThreeLac. You and your partner may want to give it a try and see if it helps you. You both should really take it because it is said that if one person in a household has Candida, chances are everybody does. I like ThreeLac because it's all natural, and also because it's so easy to use (powder packets that you swallow), and it was easy to get my partner to use it as well because of this. You might want to give it a try -- it gave me a new life. If it doesn't help you, then I would continue to pursue assistance from a qualified medical professional. Good Luck.
