First time charting... Help?

Je

Okay, so this is my first time charting, our first time trying, AND I literally just got off of BC this month. I got my BBT thermometer and OPK in the mail and immediately tested positive on CD 15, and have been doing my best to chart since then.

I know there are days and info missing, but our wedding was on November 4th (CD 23, 8 DPO), so things were a little crazy leading up to the wedding. Anyway, I started having very light pink spotting yesterday and there is still residual brownish spotting today (only on the first wipe or two), 10 and 11 DPO.

So how does my chart look? Could that dip on 8 DPO indicate implantation? If so, is it normal for implantation bleeding to occur a couple of days later?

SO MANY QUESTIONS.
