Positive ovulation?

Shay

I felt twinges and sharp pains today. First month of <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> with OPK's. Is this a positive? Does this mean I am currently ovulating? Or I won't ovulate until another 24-48 hours? Should I BD now? Or wait? Thanks!
