Weird CM during TWW

My husband and I are trying for baby #1 and this is only the second or so month of actually trying and not just guessing when I ovulate. So the entire two week wait (today is 7DPO) every couple of days I have had a little brown discharge. It's not a lot and it's just enough to notice after I wipe. I don't remember this happening before so I wondered if this was what implantation looked like or if maybe I'm crazy and it's just normal to have discharge that color anytime. Anyone else have this or noticed this before they found out they were pregnant? Of course every little thing I think could be a symptom so trying not to be that way but it's hard.
