I think I miscarried....

I’m pretty sure I had a chemical miscarriage/ pregnancy. I’m 3 DPO and I’ve been spotting and light bleeding for 3 days now. I’ve been wearing panty liners since yesterday. Only need one maybe 2 for the whole day because the bleeding is pretty light. I’m torn to pieces. Today I had a blood clot that was a little bigger than a pea. I cried my eyeballs out.... is it true that this means chemical pregnancy? Or am I overreacting.... trying for my rainbow baby so I’m praying for the best... please send good vibes. 😢
