Query about i know kit & HFA-Q10 Capsule

Query No - 1 We are visiting a gynaecologist for my wife's primary infertility problem and she also have hypothyroidism and low vitamin D3 level and also having irregular periods and our doctor suggested us HFA - Q10 from Pharma Ethics Company Capsule (which is difficult to arrange) Can you suggest any substitute of this or any other similar capsule or tablet. Query No - 2 Our doctor suggested Letroz tablet for 5 days in last cycle but that wasn't successful with Hucog 5000 IU injection and told us to repeat the same but last time she recommended USG follicular studies to detect ovulation but this time she recommended i know kit to check ovulation how can we know about ovulation with this kit while we use Hucog IU 5000 injection for ovulation. How we will know about the right time to inject Hucog IU 5000 injection. Thank You
