Miscarrying. Crazy amount of pain but almost no blood?

C
Is it normal? I have a missed miscarriage. 6 months ago I had a miscarriage but when the doctor pressed on my tummy was verry painfull. This time when I press it is not painfull, almost no bleeding at all. But the pain in mu uterus is so bad. Is it normal? My baby died almost 19 days ago. Could it be the beggining of an infection?
