Chemical pregnancy and still getting BFPs

Andrea • Mommy to Eleanor 12/14/16 💜 and Julius 9/26/18 💚, expecting Penelope 2/17/22

It's not confirmed yet, so I don't know if it's normal discharge early in pregnancy or a period yet. I have 23 day cycles and it always starts with light, brown discharge. Which happened this morning, on schedule. However, I got a squinter BFP the evening of 8dpo (not in the morning, though). 9dpo was faint, but there. 10dpo was darker. Today is 11dpo, no lighter than before, but not really darker or not by much. I tested positive on two different brands today. Is this a common experience for anyone else? Getting BFPs as your period starts?
