Chemical pregnancy😭

Lovely

Ladies 5 days ago I got a positive pregnancy test and I had some old brown blood discharge but only when I wiped and I supposed to get my period 5 days ago but I took a test again today and came up negative does it mean I’m having a chemical pregnancy? I didn’t started to bleed yet. I’m so devastated I had a miscarriage last year November, I thought this is gonna be my rainbow baby.
