There's really no way for us to know because it is flu season and you just started cleansing. Could be either or both. Either way, you are under the weather so treat yourself as if you have a cold or flu. My mom got a raging UTI from DE because her body could not eliminate all the toxins it was stirring up fast enough before it resettled in her UT. Ease up on all the stuff you're taking while you are feeling bad. It's not a race and cleansing is better to do "slow and low" as I like to call it. Take care of yourself and feel better before you start up again. It was probably too much too fast. Don't give up! Just take it easy for a week or so. Good luck!
