Ok, got AF on CD 32 this month, which may be a sign I am starting to regulate. Previously it was CD 31, 37, and 49 from coming off BCP. We are going to "officically" try in July, but I want to start using the OPK for June. So, when should I start and if I only have 7 sticks, should I buy more for this month? I have the CBE digitals. TIA!!
