8DPO, implantation dip?

Here is my chart so far. I'm really hoping that today's dip is an implantation dip. My bbs have been extremely sore and tender, and I've been very tired. Other than a little cramping, bloated feel, I've been feeling pretty good. I can't wait until Monday. I almost poas this morning, but I know it'd be a waste. I mean, Monday may be too soon anyways. I'm just really hoping for an answer soon!!!! • A fertilized blastocyst will implant itself into the uterine. The point of implantation becomes the origin for the placenta and umbilical cord. Note that impantation can occur today, but also several days from now...
