Fertility help

Hoping for a little help. Is there anything besides vitamins that I already take daily I can buy to boost my cycles routine and help in ovulation that anyone could recommend without help from Dr? My gynaecologist won't help me until I have tried for a year or more naturally so would like to try and booat my chances best I can that isn't just eating right, taking vitamins and looking after myself. My cycle is all over, some months I bleed for 5 days others I can go up to 13/14 over my OV day. Been trying and tracking for 6 months to no success. I lost my 7 week old daughter Hope sep 20 and desperately want our rainbow baby 🤱🌈 I fell pregnant so quickly with both my girls and every month I take a test I feel so defeated, such a failure and that maybe it just wasn't meant to be 😔
