Irregular cycles

Kaite
My cycles  (3 months off BC) have been 30 days 32 days and 35 days. I have used CBE digital advanced tests and have gotten 6 days of high smile but no peak yet-- starting to worry I won't O this month :(
Sidenote I have been having random sharp (but not very painful) pains that last 2 seconds or so in my lower right abdomen near my hipbone-- has anyone ever had those as a sign of ovulating?
Any advice appreciated!!
