Spotting

I️ spot on and off of brown discharge (not red) qfrom about 4dpo to onset of period which only is 2 days and medium flow. So I spot for about 8 days on and off light/medium. I️v had this for years and never really thought anything of it. It’s my third month ttc and in tww right now. If I️ don’t get pregnant should I go to obgyn and have this worked up or should I️ wait it out until we have been trying longer. Anyone experience this and have advice? I’m worried about this. Like is this still conducive to conception?
