Spotting 9dpo monthly

Hi everyone,

Curious if anyone else has spotting almost every month around the middle of their LP? I am 99% sure it is not implantation bleeding. Never had it with my first pregnancy and I’ve had spotting around 7-9dpo in other months and have not wound up pregnant. I think maybe I should go see my doc, but I’d like to have an idea of what to ask her about? So would love to hear from anyone else who’s experienced this and what ended up being the issue??

Thank you 🥰
