Hello, Resistance to antibiotics develops over a period of time. It depends on various factors that include dosage, time of use etc. Because you had to use them for specific reasons as a part of targeted treatment, Getting medical guidance and using antibiotics under medical supervision helps to prevent the development of resistance. So, there is only a mild to moderate chance of developing resistance. I understand your concern regarding your immunity.
