Fearing the worst

Justine
I had my first mc in September at 6w1d. 
I went to the ER at 5w6d for some bleeding. We saw a baby and a heartbeat so everything seemed to be ok. 
Today (crazily enough at 6w1d) I gushed blood and had to change my pants and my underwear. I went to the bathroom and when I sat down, more gushed out. I'm having a lot of lower back pain but not really any cramps. 
I'm worried that I'm having another mc. 😥
