Bloody show or irritation from check?

Hate to be that person but how do you tell if you are having your bloody show or just having slight bleeding from being checked for dilation? I was checked roughly 3 and half hours ago and was only 1 cm dilated. I have went to bathroom multiple times and didnt have anything but when I went to bathroom just now had what looked like slightly bloody discharge. Not sure if it's from being checked or its bloody show
