Cramps after miscarriage

Can anyone tell me if they are having or have had any discomfort in their lower abdomen area after a miscarriage? Like two inches below my belly button and to my left I have pretty constant pain and when I press on it it's pretty painful. This is my  first MC. I don't even know the true date of my MC, based on bleeding I would say around March 28th or so, But this particular pain only started a few days ago....anyone???
