Is it possible to know when ovulation is well and truly over? I understand we can ovulate anything from 8 to 48 hours after a +OPK which i totally understand.(or not at all even with a positive) But how do we know when ovulation is over? I usually have EWCM the day after a +OPK and then i go completely dry till AF - and i assumed my ovulation would be over based on going from EWCM to completely dry..
