Yeast Infections

So last month I got a yeast infection, treated it with antibiotics, 4 days later it was gone and no more symptoms. This month I got another one, almost one month apart to the day. It is right before my period, which I know is something that happens. I've also been eating more sugar than usual and less "real" food. I have a new partner too... as well as going off birth control... I know yeast infections are pretty common but I feel like getting two close together isn't a good thing, should I be worried? I took Monostat 1 and it's helped a lot, but if it isn't clear by tomorrow I'm going to the doctor for antibiotics again.
