Ovulation post chemical

Hey guys . . I had a chemical last cycle. I had several days of faint lines and eventually a late period. Now , if I count from the first day of bleeding after chemical it is CD 15. I haven't ovulated yet. Does anyone have experience with post chemical ovulation? Will it be late or not at all? I was hoping to ttc again (second month trying) but am afraid I won't ovulate at all.
