Is it normal?

I started my “period” 2 weeks early I thought I ovulated the 30th of Jan so we BD every other day and then at what I thought was 6dpo I had some light pink spotting on and off all day so I thought maybe implantation bleeding because 2 previous pregnancies I had it and then I just kept bleeding and bleeding very lightly not even hitting a pad and then day 4 and bam blood running down my legs idk what the deal is I’m just confused and had my hopes up because we have just had a miscarriage on May 4th 2020 💔😔 please don’t me mean
