Implantation bleed?!

Britt

So I'm 9dpo today. Been feeling crampy the last three days. I've also had a dip in bbt on 6 dpo and 8 dpo, and temps shot right back up in between. Today, I felt some discharge (and I've been having creamy almost milky white discharge which is totally NOT normal for me--usually I just dry up after O). So I noticed the discharge was brown and then I wiped and I've been spotting brown discharge for about an hour.

Could this be IB???

For those who had IB, does this sound like it?

My boobs are also really sore, acne flaring up, have hot flashes, nausea at random, backaches, dizziness, etc over the last three days.
