Bleeding and cramping but HCG is going up

Misty

On December 26th I go two positive pregnancy test. Then on December 28th I started bleeding and cramping. I went to the Er and my HCG was 42 and they told me to come back in two days to see if the number was going down. I went back and my number tripled. I am still bleeding and cramping but they said it’s a good sign. I’m doing my best not to stress but this is hard. Has anyone else had this happen?
