Go back to the er they need to find out why u are still bleeding !!! Is it heavy or just spotting? I don't want to scare you or worry u but my test also came back positive when I was going through my miscarriage!!! I pray that that's not happening to you!! In my prayers and good luck to you
And try not to stress I no easier said then done but try and stay off your feet and drink a lot of water that could help with the cramping!!
Go get checked out again it's not normal to bleed and even though you tested and it's positive that doesn't mean you're not having a miscarriage your hcg won't drop to 0 till the fetus is gone
