Do i need the trigger shot?

Anna

I am currently taking leteozole. Just started back on it in December after my 2nd miscarriage. Started this round yesterday. I have been on both clomid and leteozole a combined total of about 10 months in the last year and half. My obgyn has never done a ultrasound or trigger shot while i have been on the medicine. Are there many woman who only take the medicine and not get the shot?
