Spotting vs implantation

Kaitlyn
Hi ladies. so I have a quick question. I started to have brown discharge on 5dpo. Today I'm 9dpo and I still have it. The thing is **TMI** it isn't coming out on to my underwear or even when I really wipe. I wouldn't even know it was there if I wasn't regularly checking CM. I have put toilet paper up there a bit and its on there but I still have yet to have any come out onto a panty liner or underwear. Does anyone know what this is? My hubby and I are TTC (month 1). I thought it might be IB but I feel like 5days worth is too long? Please help 😳 has anyone ever heard of this and ended up being PG? I took a test yesterday at 8dpo and it was Bfn. Thanks!! 😊
