Maybe a silly question...

But I've been sick for the last three days, haven't had much to eat at all, trying to stay hydrated but still not drinking nearly enough. And I've had LOTS of sleep (like upwards of 30 hours in last two days)...my period isn't due until Thursday or Friday but when I wiped after using the bathroom, I had some light pink blood. Could my sickness have brought on my period sooner than normal?
