Confused

Ch

I’m on my second cycle of clomid. I started at 50mg but my dr increased my dosage to 100mg this cycle. I charted the first time and didn’t see any sign of ovulation. However, I’m still not 100% on what I should be looking for. Can anyone explain it to me better? I’ve read the linked articles in temping but it still doesn’t completely make sense.
