miscarriage side effects

i’m sorry idk where to post this, i was diagnosed with a “spontaneous miscarriage” last monday and the bleeding has lightened up, no abnormal clots or anything crazy but since last night i’ve had really bad lower back pain that was enough to make me curl up in a ball, ive had what i’d probably describe as lightening crotch? on the left side of my pubic bone, ive had nausea and dizziness as well. i wouldn’t say i’ve had foul smelling discharge, i wouldn’t say it smells great but i wouldn’t assume infection?? i’m not sure though. i felt fine and bleeding is lightening up but these symptoms came out of nowhere
