Confused on ovulation?

Had a D&C; in December. Have had two normal periods since, and started charting this cycle. I’m new to the charting and I’m totally confused. Positive OPK was a little earlier than normal on cd12 (used clearblue this time), but didn’t have an actual ovulation dip until cd22? On a 28 day cycle that doesn’t give a long enough luteal phase, right? Anybody have some positivity for me? Just wanting a rainbow but pretty sure I’m out this round.
