Watery Menstration

Kayla
After having a miscarriage in September I am 3days into my period. My blood looks and feels slippery and watery. I also have passed a few clots the biggest being the size of a nickle. I have not had a D&C because my insurance won't cover it, could this be a posibity for what's causing it. Trying to get some insight on what this can be.
