at around 7-8 dpo my bbs hurt, all the way up to my collar bone it seemed! I do usually get tender breasts near my period, but nothing like this and never that early. I had a few cramps/twinges and things I thought could possibly be symptoms, but I couldn't be sure. At 9-10 dpo they seemed to magnify in intensity, and then I knew. I didn't have fertile cm around the time af was due, which was actually out of the ordinary for me, but it did stay creamy throughout the 2ww. A couple days after my bfp at 12 dpo, I did have a small glob of it though, but that was all. Also, I had a dull constant headache, and I rarely get those. I kept getting faint positives from 8 dpo on, but I'm an expert at seeing a line where there isn't one, so I couldn't really trust that. Good luck!
