I have read that once you use the strips and get a positive reading there is no need to continue as once the LH surge happens and you are going to ovulate within the next 24-48 hours, your LH surge will then begin to decline. The strips are to help you detect when, approximately, you may be ovulating. You get a dark line (positive) and then it will start to lighten thereafter so no point wasting your test strips for the remainder of that month. Hold onto them for testing next month :) Hope that makes sense.
