Implantation Dip?

Le

Last cycle was tough emotionally. I told myself I wasn’t going to get too excited this cycle. Buuuuuut...I don’t think I can help it. My temps just keep on climbing (the two highest temps I’ve recorded since I started temping maybe 4 cycles ago?) and now I’m wondering if yesterday’s dip was an implantation dip. Having TONS of watery CM, and today it includes a tiny bit or brown spotting. (8-9 dpo is usually light/creamy for me.)

What do you think?!
