Ovulation Detectors

Question

I had sex with my boyfriend on Tuesday, and he came outside that night.  The next day I came into ovulation phase and this phase has continued till today ( 12/18-12/22 I checked it through ovulens detector), why does my ovulation phase last so long, I have heard that it should be like approximately twenty four hours. I did a pregnancy test and it showed negative. I am a little bit confused, can you tell me what happened to me? What I should do next?

There are different types of ovulation detectors. They do not all measure exactly the same thing. The ovulens will detect the three to four day fertile time period prior to ovulation, from changes in the saliva, due to the rise in estrogen hormone at this time. Other types of ovulation detectors, measuring urinary LH, more precisely mark the exact day of ovulation. However, the urinary LH kits may miss detecting ovulation 10% of the time. Using an ovulation detection (or natural family planning) method to help time intercourse will increase your chances of getting pregnant, but is not a guarantee. It might take up to six cycles for a couple of normal fertility to get pregnant even if they time intercourse optimally.
