Vegan life...good or bad?

I’ve been vegan for almost 8 months now. However, I just heard of some research that says being on a vegan or vegetarian diet can really impact your chances of conceiving and cause issues during pregnancy. This is totally against what I’ve believed these past 8 months but now I’m totally worried!! What is everyone’s thoughts? Has anyone gotten pregnant and had a healthy pregnancy while being vegan (or even vegetarian)? HELPPPPP
