Anyone else? TMI (no pic)

I'm 31+4 and It seems the last 4-5 days I've had nothing but green diarrhea, gross I know! Nothing in my diet has changed and I do not take iron. anyone else experience this or did I catch something nasty? 
Oh and the weird thing is, I'm having pretty regularly timed BMs, it's just loose and green when it's time! What the heck!
