Hi ladies - all of you 24 year olds are making me feel old!

I get the "young" thing a lot at work. I'm a teacher and parents always ask me how long I've been teaching. When I say 9 years they have a look of shock on their face and often say, "you don't look old enough to have been teaching that long!" It always gives me satisfaction to let them know I am, in fact, an experienced professional!
I am worried that I didn't O but know the chances of that after the trigger shot are extremely low (like 99 to 1). I haven't been temping this month but have checked it the last few days (starting the morning before the trigger) and it's been dropping each day! From 98.0 to 97.2 this morning! I felt significant O cramps on Sunday which is when I was supposed to ovulate. They are gone now and CM has turned creamy. I've read temps are unreliable after a trigger but it's still making me paranoid!
