Where is my O?

I can't figure out when I'm ovulating, or if I even am ovulating for that matter. that is my 2nd cycle ttc after stopping my bcp's and I'm thinking maybe my cycles haven't gone back to normal? it's been so long since I haven't been on the pill that I'm not even sure what normal is! I took my last pill on May 23 and got af on the 25 until the 28 [i believe] I've been charting my bbt and cm but i can't really make heads or trails of it. Can any one offer some advice? thanks!
