Definition of an ovulation

[Julia]

Hello! Calculated day of an ovulation under the special test or dough (on urine), in one of days was two bright strias, on sledushchy day after that day again - one bright (constant), and another is hardly visible. What is it can mean? - 1) hormonal emission only once, quickly falling down 2) the ovulation passed or took place in day when there were two bright strias and was very short (hours 8 12 t) (strange why in advance then the test has not informed or notified me, it is written, what shows an ovulation for 24 48 hours)? Comment, please.

The test with two bright strias - positive. In 24-48 hours after it or him - an ovulation. The test shows not an ovulation, and the emission of a hormone PREVIOUS her. Therefore on a trace. Day, in day of an ovulation, he already negative, all is correct.
