Breastfeeding while pregnant


Anyone breastfeeding while pregnant? My local IHS tells me people nurse both babies all the time but I switched to my hometown doctor who delivered my first baby and he recommended me to stop breastfeeding. Sometimes it’s super painful and I think I might want to stop nursing her but I just emotionally feel like she or myself isnt ready to wean yet... was there any complications with being pregnant and nursing and did you nurse both after the new baby was born ???? I don’t know what to do
