You have not mentioned size of follicles. If follicles were large on day9(>12-14mm) & not seen on days 12, they might have ruptured. Don't get disappointed so early. There are good medicines(tablets & injections) available for ovulation induction
. Sometimes ovulation induction can take time. Just consult some infertility
specialist doctor who will guide you right way.
Wish you good health.
