Breastfeeding while Pregnant - Maintaining Milk Supply

Abigail

I have a 6 month old and just found out that I'm 7 weeks pregnant. I'm breastfeeding my 6 month old, but I have noticed a drop in my milk supply. I reaaly do not want to supplement with formula. Does anyone have any tips/tricks to increase supply while pregnant? Do you have experience with breastfeeding through your pregnancy? If so, were you able to it throughout your pregnancy. Looking for some ideas and positive experiences.
