Possible implantation? Confusing body...

My fertile week was from Wednesday to Sunday last week according to glow. Bd'd every other day and days since my last af that was on the 4th too, just so I didn't miss my window. Been tracking cm and cervix and all seemed normal, fertile week was mostly watery and high open soft, yesterday I noticed it was more of a ewcm or lotion type which I never got before since tracking, ttc'n for 4 months now, AF has always been long but august and September af showed on the 4th both months, before then I was always at least 37-41 days in between, never had af within 30 days... now its Oct and I'm not trying to account for af to show on the 4th, but today, I went to check like I do the same time everyday, and I had brownish pink when I wiped, check cervix and just like yesterday it's high, almost can't reach it and it's very soft, softer than my lips to where I couldn't at first tell where it was and I had the same coloration on my finger as the tp... tmi I'm sorry!! I'm trying not to get too hopeful but Google tells me it's implantation but anyone else experience this and how long did u wait for ur bfp? If I were to guess because I don't use opks, my O day based off of tracking I O'd 5 days ago. Dtd the day before and day after... any advice? How long should I wait to test? Glow calculates me to have af on the 11th so it must be too early or maybe I'm starting early again? Such a confusing body I have lol TIA ladies!
