So we have been ttc for 7 months. This cycle used OPK that showed + on CD 19 (my cycles usually 35ish days) on 9DPO I had a decent amount of pink/brown CM. since then I have maybe one episode a day of very light pink CM, but not even close to the episode on 9DPO. BFN today, but if it was implantation on 9DPO it is prob too early to test (today is 12DPO) anyone else experience this? AF? Or maybe preg?
