Next period?

I had a miscarriage Christmas Day I was 6 weeks and 2 days. I guess i could say the dr said he couldn’t find the heartbeat and that my HCG levels were low that night when i went to the ER, by Thursday my HCG levels were in the 800s, by Friday they were in the 500s, and by Tuesday they were 130. I started out with spotting then it turned to small gushes of blood then on 01/03 it was full blown heavy heavy blood. And now it’s 01/07 and it’s slowly going away still some heavy spotting every now and then. But I wanted to ask when will I have my next period? Or was it included with all the blood that came out? My first miscarriage so don’t really know anything and I really don’t feel like calling the obgyn right now bcs she had the nerve to tell me just bcs it didn’t work this time doesn’t mean it won’t work next time, right after telling me that she could no longer see a baby or sac in my uterus from the ultrasound I had done Tuesday morning. And I was crying my eyes out.
