Hello Dr, my first pregnancy was still born case due to high bp and 9mnths after delivery we started planning but no result. So went to fertility expert they suggested iui( because of reduced sperm count). Where 3 iui cycles was unsuccessful and as per dr suggestion went for ivf and after 14days wait beta hcg value was <0.1. 1. What factors impacting my pregnancy and what further investigation need to be done? 2. Is it good to go next ivf or any better options then this?
