I was diagnosed with a UTI 48 hours ago, I started the prescription of macrobid by ten am. That evening I noticed a thin milky discharge, that was not part of my usual cycle. Has anyone else experienced this? It doesn't have an odor, just a continuous ooze that I have to use a panty liner for. Any feedback would be much appreciated, my doctor just said it could be a side effect, but mainly brushed me off.
