period after miscarriage

Je
I had my misscarriage on May 30th, so not quite three weeks ago. 
I've never truly stopped spotting. I would spot brown typical once later in the day. Today I noticed bright red blood and I'm having to wear a pad. 
Could this be aunt flow? I wasn't far along when I lost the baby. I was ten weeks but baby only measured 6 and my number dropped quickly. 
I'm confused if this is my period or bleeding related to the misscarriage 
Is there signs I should look for??
Thoughts???
