early miscarriage

So around when my period was due at the begining of August I started to experience heavy bleeding and cramping which I thought was normal period...only lasted a few days and then for the last 2 weeks been lightly bleeding on/off with some brown / pink discharge. Took a PT a few days ago (2 weeks after the bleeding and cramps) and came up with a bfp. Saw GP and she thinks it might have been an early miscarriage- now have really sore boobs and random cramps/twinges in various areas of my tummy but still bleeding- wish it would stop now! 😞
