Am I losing the baby?

I’m 4 weeks 5 days

I’ve been spotting for three days and it turned red and there’s a tiny clot. Chemical? Nothing to worry about? Go to a doctor?

Update:

Spent the morning at the ER. Bloodwork showed hcg 47 and an empty uterus. All day cramping and bleeding. Doc called it a threatened miscarriage for now and in two days I go back to see if hcg is gone.
