Spotting and pcos questions

Hi! I have pcos and I’m currently ttc my first baby! My husband and I have been trying for about 4 months and I’ve only ovulated once in that time span (a little over a month ago). It didn’t seem to stick but we’re not losing hope! For the past 1 1/2 weeks I’ve been experiencing very light, rusty brown spotting every single day. No positive ovulation or pregnancy tests in the last 2 weeks. Any thoughts on why it’s happening/ when should I be concerned? I over think everything so I figured I’d ask you all before I bother my OBGYN😂 thanks!
