Please help!😩

So I exclusively breast feed my 2 1/2 month old. I just got diagnosed with Mastitis the other day and am on antibiotics 4 times a day for 2 weeks. And now my vagina is red, irritated and sore. I think I may be getting a yeast infection although those are the only visible signs. What can I take to treat it while breastfeeding?

Side note: I started taking a probiotic when I started the antibiotic
