Breastfeeding while pregnant

My daughter is almost 9 months and I’m really ready for another baby. I was trying to wait until she turned 1 but i really wanna start trying now. I am also breastfeeding. So i was wondering will my milk supply stop if i become pregnant while breastfeeding? Are there any moms who have successfully breastfed while pregnant? I wanted to breast fungus she’s one also. Can i start trying right now or should i hold off until she’s 1?
