possibly early miscarriage????

Brittany

So my period started 5 days early, which never happens and now has so far lasted 7 days. Today though small black look chunks came out. I've had miscarriages in the past but not for years, internet is unhelpful. I'm not on bc but still now "trying". No extra painful cramps. But have had a headache from hell the ladt 6 days, dont know if its connected. What do you all think ? Possible stress issue? Miscarriage? Ideas?
