I purchased 2 kinds of the OPK tested 3 day in a row both brands showed postive. to day it is negative can you please tell me if ovulation occured with in thoes 3 days or will it occur with in 24 hours after the LH surge stops.
Usually, it is advised to stop testing once you see the first Positive OPK. Once you see the first Positive OPK, ovulation occurs within the next 36 hrs.
