Yeast infections :(

Since February of 2018 I’ve had back to back yeast infections and it’s terrible. I’ve tried home remedies, Monistat 3&7 as well as probiotics and lastly antibiotics. For well over a year now I haven’t gone more than a week without discharge or some minor itching. I’ve been checked multiple times for everything and I’m clean. I don’t understand why it won’t go away. Sex can be painful and I’m embarrassed that I have to deny any sexual advances to my partner because of it. Any advice? ☹️
