advice needed about possible implantation

Emily

Okay, so today I am what I think too be 8dpo. Mind you I never got a positive Ovulation test it was just a smidge lighter so there's every possibility I could have missed the surge. I did have ewcm and also had a very open cervix so I gonna go by that. On 6dpo I was checking my cervix and noticed brown discharge. I had wiped and didn't see anything, so I popped a tampon in for just a few seconds and pull it out and there was quite a bit of of brown mixed with some mucus. Spotted brown with little touches of pink most of the day but again it's never been enough too come on toilet paper only when I check with a tampon. So on 7dpo was light pink the couple of times I checked it once it had a little bit of red mixed in in there was nothing when I checked last night before bed. Wake up this morning on 8dpo and small amount of red and again only when I check with a tampon. Not dark red but red. Could this be implantation or my period a whole week early?  I'm driving myself insane. Lol and just need some relief. I use first response this morning and it was negative. I wanted too do clomid this cycle so idk if that would considered cd1 or not. Just need some advice please 😊 also symptoms have been very mild dull on a off not really cramping kind of like a pressure in my pelvic area, headaches, horrible acne and 1 tender breast lol, and have napped the past 2 days. Thanks in advance.
