Confused...

Hubby and I have been ttc for 3 years, I have pcos and our first fertility appointment is this upcoming Thursday. So the reason I am confused is because I am 8 dpo and on my 4th dpo I started lightly bleeding and have been bleeding since. I am still lightly bleeding and very confused. My period is very regular never late or early so there’s no way my period was 10 days early. Just wondering if anyone has any knowledge of this or knows anyone who has gone on to have a bfp in my circumstance. Thank you for reading 💕💕💕
