Just need some advice- I have been using OPKs since CD10, with progressively darker lines until CD16-17 with another darker on CD19. I had lots of EWCM CD12-17, then CD18-20 more creamy. Lots of OV pain on CD16 and bloating on CD18. Spot of dark brown blood last night in undies (CD20). I am using vitex and it seems to be working to shorten my cycle based on CM (last 2 cycles 35-41 days), but still no positive OPK. Did I miss it? I have been BDing everyday since CD14 to cover my bases Not temping as I always forget in the morning!
