Hi there, I was diagnosed with a UTI and was prescribed Macrobid. I have been taking 2 a day as prescribed. I have 3 pills left. I began noticing vaginal itching Tuesday night, so much that it woke me up in the middle of the night. Today, partnered with the itching, I am experiencing some light discharge. Is this normal? It has been years since I have taken Macrobid, but I do not remember having these side effects.
