Yeast infections

My husband and I are trying to conceive and have been for about 7 months. Every month after my ovulation days, (after we’ve had sex twice a day and he has cum inside me) I’ve been getting a yeast infection. EVERY MONTH!!! I’m so over it. Could I have an allergy to his fluids? I am super clean. I shower and wash daily. I don’t understand... he ya no symptoms or signs of having a infection or anything. So I don’t think he’s giving it to me. Ugh any suggestions? Anyone else experience this?
