Period or MMC?

Katti

Monday I started bleeding and cramping pretty bad at 5 weeks 3 days. I called my doctor and he said to treat it as my period. I am so confused. I took 5 pregnancy test and they were all positive. I am not sure what he meant by treating it as my period. Im just a little concerned because I had a MMC in Feb and I don't know if I had another miscarriage on Monday or if it was my period that came on. HELP!
