Pregnancy after miscarriage(s)... any success stories to share?

Delivered in 2018, miscarriage in 2019 and 2020 (both within 8weeks). Im pregnant now and edd April 2021. With health first born, doctors are puzzled as to why so the only reason Ive been given was that its unhealthy pregnancies hence our body auto terminate it. What I notice is, ive been going to tcm for all pregnancies but only the healthy pregnancies my husband went to tcm with me. So we have concluded that tcm helped his sperm quality. I wish you luck!
