I am 31 year female with pcos and my husband having 52 million sperm count and 40%motility. He is using clomiphine and cq active from 2 months. And I am under letrozole second cycle. On cd 11 I had an ultrasound scan and doctor told me no need of triigershot this month asvi had it on last cycle. Is there any chances of conceiving with only letrozole and no triggershot?
