First time using OPK -- have i ovulated?

[shelleyanddan]

Two days ago i got my first positive opk (test like darker than control line). Yesterday it was also positive and I was having some lower abdominal pain kinda felt like a full bladder or uti...

Today opk is negative, but seems a bit early for O as i have a reg 33 day cycle, O day should be in another 3 days!?

Judging by the opk results, do you think i have already ovulated???

Also, no temp changes yet..


Any help would be appreciated!!
