Bleeding but hcg test getting darker?

Hi! So I had a vvfl at around 10 dpo, started having brown discharge and dark red bleeding with small clots. Bleeding is not as heavy as AF, no cramping noted so I kept on testing my hcg and I’m 12 dpo now and it just kept on getting darker than 2 days ago. I have not seen my doctor yet. Has anybody had this experience before?
