Spotting for a month?

Hello. I’ve been spotting for a month now. It’s mostly like blood tinged cervical mucus. I had a few days in the first week that seemed like a very light period but it’s been just spotting ever since.

I’m wondering if it’s hormone related since we just lost my younger brother in a car accident at the end of September.

I have an annual OB appointment coming up, so I’m planning on talking to her, but I’m just curious if anyone has experienced this sort of thing before.
