Clear Fluid During My Period? I Had An Iud As

Clear fluid during my period? I had an iud as birth control for 7 years. My first period last month after taking it out was normal. This month I started my period and for two days I was soaking through super + tampons every 1/2 hour. Now today I'm not soaking through but I keep feeling like I am and when I go checkmated it is clear liquid. Almost as if I had peed my pants but I didn't. What is this and is it normal?
