Need a suggestion for yogurt/probiotics

Hoping someone has some suggestions. Please don’t judge me, I don’t have health insurence and don’t have money to go to the doctor, but I definitely have strep throat. My tonisils have always given me issues and I had strep a lot growing up so I definitely know the signs and what it feels like.

Luckily, my mother in law has some amoxicillin left over from her last strep, so I’m taking those. But I already know antibiotics are going to give me a yeast infection, they always do. So I plan on getting some probiotics and yogurt, any suggestions on which brands and strains are best?

EDIT: I understand it may be concerning that I’m taking leftover antibiotics, but it’s like this: I have 2 choices. I can go to a urgent care or emergency room which will cost me thousands of dollars, or I can pay my bills and take whatever medicine I can get. The antibiotics I’m taking are amoxicillin which is the exact same milligram, type and even look as the antibiotics I’ve been prescribed before. I understand they’re prescribed for a full cycle but every time I’ve ever had strep, I’ve only ever needed maybe half the bottle and the strep goes away. My tonsils are just easily irritated so it come back during allergy and cold seasons. But that’s all besides the point, I know what I’m doing and what I’m asking for suggestions how to avoid side effects that come with antibiotics IN GENERAL.
