D&C heavy bleeding

I found out I had a miscarriage on 12/12- had a D&C; on 12/15, I had light spotting after the procedure and no cramping and was glad everything seemed To go fine. Now yesterday, and today all day I’ve been having the worst cramps ever! Even worse than when I get period. Also bleeding a lot when I pee and clots, but not big clots about size of dime. Now I notice jelly like blood coming out of me in toilet... the consistence is literally like jelly it’s gross. I called my doc they said unless I have a fever or really heavy heavy cramping and bleeding through a pad every hour, that its normal. This was before the jelly like stuff though. Anyone every experience this?? Seems too soon to have my period as procedure only happened less than a week ago but these cramps are awful and so is the bleeding. Wondering if they didn’t do the procedure right or did they leave smtnng in me?? Any feedback is appreciated!!!
