We are TTC from last six months. Last month doc prescribed my wife, fertyl 50 for the first 5 days of her cycle. On cd12 she had a follicle of size 23/19. On cd13 doc gave her a hcg trigger shot. Today is cd25 and the ovulation has not occurred even after the trigger shot. Doc has told to repeat the same medication in the next cycle. We would like to know how common is it to not ovulate even after the trigger shot? We are a bit worried what are the chances of successful ovulation in future. Please advise. Thanks.
