Spotting and still BFP?

I spot every month usually starting about a week before my period. Which always makes me hopeful that it’s implantation bleeding then my period shows up. The only time I didn’t spot like this were the cycles I got pregnant. Has anyone spotted like this each month and even spotted the cycle you got pregnant? Would love to hear some positive stories because I’m already feeling out this month. I’ve read that you can spot regardless.

Also - progesterone has been checked and it’s normal. I have endometriosis but my cycles are very normal and have mild endo.

This month I’m having all these pregnancy symptoms and had cramping at 8dpo then 9DPO light pink spotting that turned to very light brown (barely see it on toilet paper) that only shows when I wipe. At 10dpo the spotting seems to be getting less and less.

Thank you!
