Why does it hurt so much

Lyce

Last November I suffered a miscarriage I believe I had a chemical pregnancy I took 11 test all positive. But he say my period was supposed to come down it passed with it. Now on December 29th 2017 I took 6 all positive I got super excited scheduled my first appointment and all so now it’s January 7th 4:40 am I’m awoken by pain cramping as if I’m menstruating I believe I’m miscarrying why does this keep happening to me ....it’s like every time I tell my boyfriend it happens the next day I dont understand this hurts so much
