Stomach bug messing with my period?

Jessica • 29; mommy

Usually my period lasts 5-7 days, the last days tapering off into brown spotting. But this week I got a bad stomach bug with just awful diarrhea (I work at a daycare) and I had medium bleeding for two days then light bleeding the next day then it stopped. I was also WAY more emotional than usual but that could just be because I was so uncomfortable from being sick? Is it normal for illness to mess with your period?
