yeast infections every month?

Could getting a yeast infection be interfering with me ttc? I've had one each month for four months, we've been ttc six months with no luck. I've seen my obgyn and she just wrote me off some prescriptions to get filled when I get them. I'm not on antibiotics or anything like that so it's strange. But anyway could this have any effect on me conceiving this month? Thanks in advanced!
